--map-syntax takes just one value

This adds a `-m`/`--map-syntax` option that allows users to (re)map
certain file extensions or file names to an existing syntax.

For example:
```
bat --map-syntax .config:json
```

The option can be use multiple times. Note that you can easily make
these mappings permanent by using `bat`s new configuration file.

+### Automatic paging
+
+`bat` can pipe its own output to `less` if the output is too large for one screen.
+
+### File concatenation
+
+Oh.. you can also use it to concatenate files :wink:. Whenever
+`bat` detects a non-interactive terminal, it will fall back to printing
+the plain file contents.
+
+## How to use
+
+Display a single file on the terminal
+
+```bash
+> bat README.md
+```
+
+Display multiple files at once
+
+```bash
+> bat src/*.rs
+```

+Read from stdin, determine the syntax automatically
+
+```bash
+> curl -s https://sh.rustup.rs | bat
+```
+
+Read from stdin, specify the language explicitly
+
+```bash
+> yaml2json .travis.yml | json_pp | bat -l json
+```
+
+
+As a replacement for `cat`:
+
+```bash
+bat > note.md  # quickly create a new file
+
+bat header.md content.md footer.md > document.md
+
+bat -n main.rs  # show line numbers (only)
+
+bat f - g  # output 'f', then stdin, then 'g'.
+```
+

+(`libz-dev` or `libz-devel`) in order for the build to succeed.
 
 ## Customization
 
+### Highlighting theme
+
+Use `bat --list-themes` to get a list of all available themes for syntax
+highlighting. To select the `TwoDark` theme, call `bat` with the
+`--theme=TwoDark` option or set the `BAT_THEME` environment variable to
+`TwoDark`. Use `export BAT_THEME="TwoDark"` in your shell's startup file to
+make the change permanent.
+
+If you want to preview the different themes on a custom file, you can use
+the following command (you need [`fzf`](https://github.com/junegunn/fzf) for this):
+``` bash
+bat --list-themes | fzf --preview="bat --theme={} --color=always /path/to/file"
+```
+
+`bat` looks good on a dark background by default. However, if your terminal uses a
+light background, some themes will work better for you. For example, the `GitHub`
+theme is made for light backgrounds. You can also make your own theme by following the
+['Adding new themes' section below](https://github.com/sharkdp/bat#adding-new-themes).
+
+### Output style
+
+You can use the `--style` option to control the appearance of `bat`s output.
+You can use `--style=numbers,changes`, for example, to show only Git changes
+and line numbers but no grid and no file header. Use the `BAT_STYLE` environment
+variable to make these changes permanent.
+
+### Adding new syntaxes / language definitions
+
 `bat` uses the excellent [`syntect`](https://github.com/trishume/syntect/)
 library for syntax highlighting. `syntect` can read any
 [Sublime Text `.sublime-syntax` file](https://www.sublimetext.com/docs/3/syntax.html)
-and theme.
+and theme. To add new syntax definitions, do the following.
 
-To build your own language-set and theme, follow these steps:
+Create a folder with syntax definition files:
 
-Create a folder with a syntax highlighting theme:
+```bash
+BAT_CONFIG_DIR="$(bat cache --config-dir)"
 
-``` bash
+mkdir -p "$BAT_CONFIG_DIR/syntaxes"
+cd "$BAT_CONFIG_DIR/syntaxes"
+
+# Put new '.sublime-syntax' language definition files
+# in this folder (or its subdirectories), for example:
+git clone https://github.com/tellnobody1/sublime-purescript-syntax
+```
+
+Now use the following command to parse these files into a binary cache:
+
+```bash
+bat cache --init
+```
+
+Finally, use `bat --list-languages` to check if the new languages are available.
+
+If you ever want to go back to the default settings, call:
+
+```bash
+bat cache --clear
+```
+
+### Adding new themes
+
+This works very similar to how we add new syntax definitions.
+
+First, create a folder with the new syntax highlighting themes:
+```bash
 BAT_CONFIG_DIR="$(bat cache --config-dir)"
 
 mkdir -p "$BAT_CONFIG_DIR/themes"
 cd "$BAT_CONFIG_DIR/themes"
 
-# Download a theme, for example:
+# Download a theme in '.tmTheme' format, for example:
-git clone https://github.com/jonschlinkert/sublime-monokai-extended
+git clone https://github.com/greggb/sublime-snazzy
 
-# Create a 'Default.tmTheme' link
+# Update the binary cache
-ln -s "sublime-monokai-extended/Monokai Extended.tmTheme" Default.tmTheme
-```
-
-Create a folder with language definition files:
-
-``` bash
-mkdir -p "$BAT_CONFIG_DIR/syntax"
-cd "$BAT_CONFIG_DIR/syntax"
-
-# Download some language definition files, for example:
-git clone https://github.com/sublimehq/Packages/
-rm -rf Packages/Markdown
-git clone https://github.com/jonschlinkert/sublime-markdown-extended
-```
-
-Finally, use the following command to parse all these files into a binary
-cache:
-
-``` bash
 bat cache --init
 ```
 
-If you ever want to go back to the default settings, call:
+Finally, use `bat --list-themes` to check if the new themes are available.
 
-``` bash
+### Using a different pager
-bat cache --clear
+
+`bat` uses the pager that is specified in the `PAGER` environment variable. If this variable is not
+set, `less` is used by default. If you want to use a different pager, you can either modify the
+`PAGER` variable or set the `BAT_PAGER` environment variable to override what is specified in
+`PAGER`.
+
+If you want to pass command-line arguments to the pager, you need to create a small shell
+script as a wrapper, for example
+
+```bash
+#!/bin/bash
+
+less --tabs 4 -R "$@"
 ```
+(put this in a file `~/.bat-pager.sh`, make it executable `chmod +x ~/.bat-pager.sh` and use
+`export BAT_PAGER="$HOME/.bat-pager.sh"` in your shells `rc` file)
+
+**Note**: By default, if the pager is set to `less`, `bat` will pass the following command line
+options to the pager: `-R`/`--RAW-CONTROL-CHARS`, `-F`/`--quit-if-one-screen` and `-X`/`--no-init`.
+The first (`-R`) is needed to interpret ANSI colors correctly. The second option (`-F`) instructs
+less to exit immediately if the output size is smaller than the vertical size of the terminal.
+This is convenient for small files because you do not have to press `q` to quit the pager. The
+third option (`-X`) is needed to fix a bug with the `--quit-if-one-screen` feature in old versions
+of `less`. Unfortunately, it also breaks mouse-wheel support in `less`. If you want to enable
+mouse-wheel scrolling, you can either pass just `-R` (as in the example above, this will disable
+the quit-if-one-screen feature), or you can use a recent version of `less` and pass `-RF` which
+will hopefully enable both quit-if-one-screen and mouse-wheel scrolling.
+
+If scrolling still doesn't work for you, you can try to pass the `-S` option in addition.
+
+## Using `bat` on Windows
+
+`bat` mostly works out-of-the-box on Windows, but a few features may need extra configuration.
+
+### Paging
+
+Windows only includes a very limited pager in the form of `more`. You can download a Windows binary
+for `less` [from its homepage](http://www.greenwoodsoftware.com/less/download.html) or [through
+Chocolatey](https://chocolatey.org/packages/Less). To use it, place the binary in a directory in
+your `PATH` or [define an environment variable](#using-a-different-pager).
+
+### Colours
+
+Windows 10 natively supports colours in both `conhost.exe` (Command Prompt) and PowerShell since
+[v1511](https://en.wikipedia.org/wiki/Windows_10_version_history#Version_1511_(November_Update)), as
+well as in newer versions of bash. On earlier versions of Windows, you can use
+[Cmder](http://cmder.net/), which includes [ConEmu](https://conemu.github.io/).
+
+**Note:** The Git and MSYS versions of `less` do not correctly interpret colours on Windows. If you
+don’t have any other pagers installed, you can disable paging entirely by passing `--paging=never`
+or by setting `BAT_PAGER` to an empty string.
+
+### Cygwin
+
+`bat` on Windows does not natively support Cygwin's unix-style paths (`/cygdrive/*`). When passed an absolute cygwin path as an argument, `bat` will encounter the following error: `The system cannot find the path specified. (os error 3)`
+
+This can be solved by creating a wrapper or adding the following function to your `.bash_profile` file:
+
+```shell
+bat() {
+    local index
+    local args=("$@")
+    for index in $(seq 0 ${#args[@]}) ; do
+        case "${args[index]}" in
+        -*) continue;;
+        *)  [ -e "${args[index]}" ] && args[index]="$(cygpath --windows "${args[index]}")";;
+        esac
+    done
+    command bat "${args[@]}"
+}
+```
+
+## Troubleshooting
+
+### Terminals & colors
+
+`bat` handles terminals *with* and *without* truecolor support. However, the colors in the syntax
+highlighting themes are not optimized for 8-bit colors and it is therefore strongly recommended
+that you use a terminal with 24-bit truecolor support (`terminator`, `konsole`, `iTerm2`, ...).
+See [this article](https://gist.github.com/XVilka/8346728) for more details and a full list of
+terminals with truecolor support.
+
+Make sure that your truecolor terminal sets the `COLORTERM` variable to either `truecolor` or
+`24bit`. Otherwise, `bat` will not be able to determine whether or not 24-bit escape sequences
+are supported (and fall back to 8-bit colors).
+
+### Line numbers and grid are hardly visible
+
+Please try a different theme (see `bat --list-themes` for a list). The `OneHalfDark` and
+`OneHalfLight` themes provide grid and line colors that are brighter.
+

+## Project goals and alternatives
+
+`bat` tries to achieve the following goals:
+
+- Provide beautiful, advanced syntax highlighting
+- Integrate with Git to show file modifications
+- Be a drop-in replacement for (POSIX) `cat`
+- Offer a user-friendly command-line interface
+
+There are a lot of alternatives, if you are looking for similar programs. See
+[this document](doc/alternatives.md) for a comparison.

+## Syntax Highlighting in bat
+
+`bat` uses the [syntect](https://github.com/trishume/syntect) library to highlight source
+code. As a basis, syntect uses [Sublime Text](https://www.sublimetext.com/) syntax definitions
+in the `.sublime-syntax` format.
+
+In order to add new syntaxes to `bat`, follow these steps:
+
+1. Find a Sublime Text syntax for the given language, preferably in a separate Git repository
+   which can be included as a submodule (under `assets/syntaxes`).
+
+2. If the Sublime Text syntax is only available as a `.tmLanguage` file, open the file in
+   Sublime Text and convert it to a `.sublime-syntax` file via *Tools* -> *Developer* ->
+   *New Syntax from XXX.tmLanguage...*. Save the new file in the `assets/syntaxes` folder.
+
+3. Run the `create.sh` script. It calls `bat cache --init` to parse all available
+   `.sublime-syntax` files and serialize them to a `syntaxes.bin` file (in this folder).
+
+4. Re-compile `bat`. At compilation time, the `syntaxes.bin` file will be stored inside the
+   `bat` binary.
+
+### Troubleshooting
+
+Make sure that the local cache does not interfere with the internally stored syntaxes and
+themes (`bat cache --clear`).
+
+### Manual modifications
+
+The following files have been manually modified after converting from a `.tmLanguage` file:
+
+* `Dart.sublime-syntax` => removed `#regex.dart` include.
+* `INI.sublime-syntax` => added `.hgrc` and `hgrc` file types.

+.TH BAT "1"
+.SH NAME
+bat \- manual page for bat
+.SH DESCRIPTION
+bat - a cat(1) clone with syntax highlighting and Git integration.
+.SH "USAGE"
+.IP
+bat [OPTIONS] [FILE]...
+.IP
+bat <SUBCOMMAND>
+.SH "OPTIONS"
+.HP
+\fB\-l\fR, \fB\-\-language\fR <language>
+.IP
+Explicitly set the language for syntax highlighting. The language can be
+specified as a name (like 'C++' or 'LaTeX') or possible file extension (like
+\&'cpp', 'hpp' or 'md'). Use '\-\-list\-languages' to show all supported language
+names and file extensions.
+.HP
+\fB\-\-list\-languages\fR
+.IP
+Display a list of supported languages for syntax highlighting.
+.HP
+\fB\-m\fR, \fB\-\-map\-syntax\fR <from:to>...
+.IP
+Map a file extension or file name to an existing syntax. For example, to highlight
+*.conf files with the INI syntax, use '\-m conf:ini'. To highlight files named
+\&'.myignore' with the Git Ignore syntax, use '\-m .myignore:gitignore'.
+.HP
+\fB\-\-theme\fR <theme>
+.IP
+Set the theme for syntax highlighting. Use '\-\-list\-themes' to see all
+available themes. To set a default theme, export the BAT_THEME environment
+variable (e.g.: export BAT_THEME="TwoDark").
+.HP
+\fB\-\-list\-themes\fR
+.IP
+Display a list of supported themes for syntax highlighting.
+.HP
+\fB\-\-style\fR <style\-components>
+.IP
+Configure which elements (line numbers, file headers, grid borders, Git
+modifications, ..) to display in addition to the file contents. The argument
+is a comma\-separated list of components to display (e.g.
+\&'numbers,changes,grid') or a pre\-defined style ('full'). To set a default
+theme, export the BAT_STYLE environment variable (e.g.: export
+BAT_STYLE="numbers"). [possible values: auto, full, plain, changes, header,
+grid, numbers]
+.HP
+\fB\-p\fR, \fB\-\-plain\fR
+.IP
+Only show plain style, no decorations. This is an alias for '\-\-style=plain'
+.HP
+\fB\-n\fR, \fB\-\-number\fR
+.IP
+Only show line numbers, no other decorations. This is an alias for
+\&'\-\-style=numbers'
+.HP
+\fB\-\-line\-range\fR <N:M>
+.IP
+Only print the specified range of lines for each file. For example:
+.RS
+.IP "\-\-line\-range 30:40"
+prints lines 30 to 40
+.IP "\-\-line\-range :40"
+prints lines 1 to 40
+.IP "\-\-line\-range 40:"
+prints lines 40 to the end of the file
+.RE
+.HP
+\fB\-\-color\fR <when>
+.IP
+Specify when to use colored output. The automatic mode only enables colors if an
+interactive terminal is detected. Possible values: *auto*, never, always.
+.HP
+\fB\-\-decorations\fR <when>
+.IP
+Specify when to use the decorations that have been specified via '\-\-style'. The
+automatic mode only enables decorations if an interactive terminal is detected. Possible
+values: *auto*, never, always.
+.HP
+\fB\-\-paging\fR <when>
+.IP
+Specify when to use the pager. To control which pager is used, set the PAGER or
+BAT_PAGER environment variables (the latter takes precedence). The default pager is
+\&'less'. To disable the pager permanently, set BAT_PAGER to an empty string. Possible
+values: *auto*, never, always.
+.HP
+\fB\-\-wrap\fR <mode>
+.IP
+Specify the text\-wrapping mode (*auto*, never, character).
+.HP
+\fB\-\-tabs\fR <T>
+.IP
+Set the tab width to T spaces. Use a width of 0 to pass tabs through directly
+.HP
+\fB\-u\fR, \fB\-\-unbuffered\fR
+.IP
+This option exists for POSIX\-compliance reasons ('u' is for 'unbuffered'). The output is
+always unbuffered \- this option is simply ignored.
+.HP
+\fB\-h\fR, \fB\-\-help\fR
+.IP
+Print this help message.
+.HP
+\fB\-V\fR, \fB\-\-version\fR
+.IP
+Show version information.
+.SH "ARGS"
+.IP
