Since you can actually distinguish between Ctrl-H and Ctrl-Backspace in Windows we need to reintroduce the tui.CtrlH constant. On *nix systems we map all Ctrl(-Alt)-h to Ctrl(-Alt)-Backspace internally, but you can use either in --bind.
* Added tests for `LightRenderer`
* Added common SHIFT, ALT and ALT+SHIFT key sequences
* Added common CTRL key sequences
* Added common CTRL+ALT, CTRL+SHIFT, CTRL+ALT+SHIFT key sequences
* Added proper xterm META modifier handling
according to https://github.com/joejulian/xterm/blob/defc6dd5684a12dc8e56cb6973ef973e7a32caa3/input.c#L357-L375
* Fix `ctrl-backspace` and `ctrl-alt-backspace`
* Fix broken tcell tests on windows by swallowing Resize events
* Added tests for FullscreenRenderer
* Removed own fork of tcell and updated tcell to 2.9.0
tcell 2.9.0 is needed for `Ctrl-Alt-*` and `Ctrl-Alt-Shift-*` shortcuts in Windows
* Replace conditional checks with switch statements to improve readability
* Replace long conditionals with constant slices to improve readability
* Bind `ctrl-bspace` (`ctrl-h`) to `backward-delete-char` by default
Since we now distinguish between Backspace and Ctrl-Backspace, Ctrl-Backspace should trigger the same action as Backspace by default. In that way nothing changes for the user but you can bind other actions to Ctrl-Backspace when desired.
This contains one test case of each tcell.Key* event type that can be
sent to and subsequently processed in fzf's GetChar(). The test cases
describe status quo, and all of them PASS.
Small function util.ToTty() was added. It is similar to util.IsTty(),
but for stdout (hence the To preposition).
