Current state of compatibility with FZF's features

[LoricAndre]

This issue tracks the compatibility of sk with fzf's options.
Please comment with any missing discrepancy that you notice.

Note: even though we aim for roughly the same feature set as fzf, we do allow ourselves to implement the features differently from them.

WIP

• --tmux option

Planned

• Case sensitive alt-shift binds , e.g. --bind=alt-g:first,alt-G:last
• first and last actions (move to first and last line of results respectively)
• Neovim cursorline like highlighting with --highlight-line (added with fzf v0.53)
• Missing --info types, can't set --info=inline, have to use --inline-info instead, missing right, inline-right, hidden, etc.
• Missing event trigger binds such as load|start|change, eg.. --bind=change:reload(...)
• Missing actions bind|unbind to be able to rebind keys dynamically
• execute-silent, the new reload has issues with shell escaping inside () (still working on finding the exact bug/repro)
• --print-query returns nil when used with --interactive (as it's probably returning the hidden query of the non-cmd mode)
• Shell escaping inconsistencies between how {q} works between fzf and skim
• no scroll bar option (main fzf window)
• Missing some hl colors (gutter, scroll bar)
• Header color overrides ansi escape sequences (can’t have blue header and then highlight a word with a different color)

Done

• reload action
• index tiebreak
