Faster startup. Use internal bash globbing instead of external grep binary (adapter from Gentoo's `/etc/bash/bashrc` TERM checking). Insignificant on Linux, but on Cygwin this cuts startup time by 40 ms on my Core i7 laptop.
Based on the patch by Matt Westcott (@mjwestcott).
But with a more conservative approach:
- Does not use linearly increasing penalties; It is agreed upon that we
should prefer matching characters at the beginnings of the words, but
it's not always clear that the relevance is inversely proportional to
the distance from the beginning.
- The approach here is more conservative in that the bonus is never
large enough to override the matchlen, so it can be thought of as the
first implicit tiebreak criterion.
- One may argue the change breaks the contract of --tiebreak, but the
judgement depends on the definition of "tie".
Summary:
Fix adapted from [@adamheins: fzf, vi-mode, and fixing delays][1].
[1]: https://adamheins.com/blog/fzf-vi-mode-and-fixing-delays
The basic problem is that
fzf presses <Esc> to enter vi-movement-mode
(as opposed to insert mode)
and then presses a bunch of keys to set up the buffer.
But the <Esc> keypress is also the prefix for a bunch of other commands,
so Bash will dutifully wait an excruciating half-second
before actually executing this command.
Instead, we bind <C-x><C-a>, which is unused by default
and seems reasonably unlikely to be custom-bound,
to be another way to enter vi-movement-mode;
this binding is unambiguous, so fzf can use it without delay.
This change was made by just `:s/\\e/\\C-x\\C-a/gc`
in the relevant section,
after adding the actual binding and comment at the top.
This fixes the problem where a new tab page is not closed when the
following configuration is used:
let g:fzf_layout = { 'window': 'execute (tabpagenr()-1)."tabnew"' }
- Slightly more efficient processing of Options
- Do not return reference type arguments that are mutated inside the
function
- Use util.Constrain function when appropriate
If you do `man fzf > /dev/null`, you'll get the following output

Removing these `.R` macros with a newline seems to have no effect on the
page but gets rid of the error.
