[PATCH v2 0/2] completion: fix bugs with slashes in remote names

[David Mandelberg <david@mandelberg.org>]

Thanks everyone for all the reviews! I rewrote __git_dwim_remote_heads
to fork a constant number of times instead of a multiple of the number
of remotes. There are still a handful of forks, but I think they can
mostly be parallelized.

I tried to find a pure shell implementation like a few of you mentioned,
but I couldn't think of one that would work in both bash 3.2 (the
version on macOS, I think?) and zsh. The only thing I found in
https://www.bashcookbook.com/bashinfo/source/bash-3.2/doc/bash.html that
looked like it would work to implement GIT_COMPLETION_IGNORE_CASE was
the nocasematch arg to shopt, but
https://zsh.sourceforge.io/Doc/Release/zsh_14.html#index_split-13_fn_letter-S
doesn't list shopt at all.

One unintentional difference with this approach is that $cur_ is no
longer treated as a glob pattern. Was it supposed to be in the first
place though, or was that just because of missing escaping? I.e., this
no longer works to complete unique-remote-branch:

git checkout unique-remote-br*<Tab>

In my original commit message, I mentioned that HEAD was no longer
listed, but I think I was wrong about that. I think HEAD went away in a
bunch of the tests because I added another remote, so HEAD was no longer
unique. Maybe HEAD should be filtered out too, but that seems like a
separate issue for a separate patch.
