Every shell completion script (bash, zsh, fish, PowerShell) shells out
to bat to enumerate languages/themes for tab completion candidates. If
the user has wired bat into LESSOPEN (e.g. LESSOPEN='|-bat -f -pp %s'),
bat's normal pager auto-detection can engage when stdout looks like a
terminal at completion time and reflect ANSI escape sequences back into
the candidate list. The result is the issue's reproducer: tab completion
expands 'Per' to '\033[38;2;248;248;242mPerl' instead of 'Perl'.
The list-languages/list-themes calls are always meant to be machine-
readable, so they should never page. Pass --no-paging explicitly to
every bat invocation inside the four completion files. The flag is the
public alias for --paging=never (already documented in bat --help) and
is the same form completion scripts elsewhere in the codebase use.
Touches the four completion files only; no production code changes.
* feat: add word wrapping mode for --wrap flag
* Run `cargo fmt` and add CHANGELOG entry
* Add word wrap tests, update manpage and shell completions
- Add integration tests for word wrapping: basic word boundary breaking,
fallback to character wrapping for long words, line numbers, and
short lines that fit without wrapping
- Update manpage to document the new 'word' wrapping mode
- Update bash, fish, zsh, and PowerShell completions with 'word' option
- Avoid unnecessary clone of `line_buf` when word wrap is disabled
* make clippy and cargo fmt happy

Repurpose the existing --unbuffered/-u flag (previously a POSIX no-op)
to enable unbuffered input reading using fill_buf()/consume() instead
of read_until(b'\n'). This allows partial lines to display immediately
when piping streaming input like `tail -f` into bat.
- Add unbuffered field to Config and InputReader
- Add read_line_unbuffered() using BufRead::fill_buf()/consume()
- Add flush() to OutputHandle, called after each line in unbuffered mode
- Auto-disable line numbers in unbuffered mode to avoid partial line confusion
- Update help text, man page, and shell completions
- Add unit tests and integration tests
Modified the PowerShell completion script to replace the null-coalescing operator (`??` - a v7 feature) with a conditional statement compatible with PowerShell v5.1. The script now uses an if-else check for null descriptions in the language completion section.
* Add a --style=default option
* Added --style=default test and CHANGELOG entry
* Format CHANGELOG.md options with quotes

* Update help text for '--style'
* Make --style=default the default option
* Update style descriptions: "basic" -> "recommended"
* Add integration test for --style=default as default
* Update clap long help for --style
