I'm gonna add more tests to this and I don't want to touch the old stuff.
Notice that this needs to have the output of the complete_directories
test adjusted because this one now runs later.
That's something we should take into account in future.
Before this change, - was sorted with other punctuation before
A-Z. Now, it sorts above the rest of the characters.
This has a practical effect on completions, where when there are
both -s and --long with the same description, the short option
is now before the long option in the pager, which is what is now
selected when navigating `foo -<TAB>`. The long options can be
picked out with `foo --<TAB>`. Before, short options which
duplicated a long option literally could not be selected by
any means from the pager.
Fixes#5634
This tweaks wcsfilecmp such that certain punctuation characters will
come after A-Z.
A big win with `set <TAB>` - the __prefixed fish junk now comes
after the stuff users should care about.
Reviewing a PR for a completion script caused me to look at the
implementation for the `__fish_complete_directories` function. Which in
turn lead me to create this change to improve its implementation and add
unit tests for the function.
