This is based on what the official git completions do, and it's quite
fast.
Also only complete files after a "--" separator for `checkout`.
Fixes#4858.
This is much quicker - on the order of 100ms vs 50ms.
We shorten to 10 characters, which is statistically suitable - 3 out
of 600k commits in the linux kernel need 11 characters.
For usage in completion scripts.
Unlike `__fish_is_first_token` (which is probably not correctly named),
`__fish_is_first_arg` returns true regardless of whether existing tokens start with `-`
or not, to be used when an arg cannot be used with any other argument.
`__fish_prev_arg_in` is similar to `__fish_seen_...` but it explicitly
tests the preceding token only, for arguments that take only a single
parameter.
As it turns out, for some terminals backspace is \b but only when
preceded by \e.
All this makes about as much sense as the english language.
Fixes#4955.
The previous completion generation was broken for several reasons:
* ./foo would break detection of suffix due to the leading . being
interpreted an extension marker,
* ./foo would be completed as foo, which would be excluded from
matching inrcomplete.cpp
Using `git for-each-ref` both simplifies the code (no need to deal
with detached heads anymore) and speeds it up.
With 1600 branches, the time goes from ~48ms to ~16ms.
- fix capitalization
- shorten descriptions
- implement subcommand shortcuts
- add arg completion for 'limit' and 'depth' switches
- improve arg completion for list subcommand in case of -p switch
bower was calling `__fish_should_complete_args`, the old name for
`__fish_should_complete_switches.`
yarn was parsing bower.json instead of package.json.
To be used by completions to directly determine whether it is either
possible or preferable to complete a switch (instead of a subcommand),
(presuming that switches must come before subcommands).
* __fish_can_complete_switches: we are in a position where a switch may
be placed.
* __fish_should_complete_switches: we're in a position to accept a
switch and the current token starts with `-` so we have no choice but
to do so.

`all-the-package-names` is still used to generate completions for `npm`
if it is installed, but it is not manually installed nor updated. It is
now the user's responsibility to do both, and it must be installed
globally.
`npm search` was _way_ too slow to be used for dynamic completions, so
using a cached list of all avaialable NPM packages to match against.
This is a bit brave for a fish completion, but the npm package
`all-the-package-names` has a list of, well, all the package names
avaialable for installation via the default npm registry. Installing a
copy locally to $HOME/.cache/fish/npm_completions and using that to
search for packages matching the tokenized command line.
Preference would be to call `__update_atpm` in the background, but that
emits an ugly "job has completed" message..
Should also use this for completions for `yarn add`.
