[PATCH 0/3] completion: fix bugs with slashes in remote names

["David Mandelberg via GitGitGadget" <gitgitgadget@gmail.com>]

Previously, some calls to for-each-ref passed fixed numbers of path
components to strip from refs, assuming that remote names had no slashes in
them. This made completions like:

git push github/dseomn :com

Result in:

git push github/dseomn :dseomn/completion-remote-slash

With this patch, it instead results in:

git push github/dseomn :completion-remote-slash

In addition, the change to __git_dwim_remote_heads() restricts it to only
list remote branches, not HEAD. I think that actually improves the
completion where it's used though, since HEAD doesn't seem to be valid
anyway:

$ git switch HEAD fatal: a branch is expected, got 'HEAD'

David Mandelberg (3):
  completion: add helper to escape strings for fnmatch
  completion: add helper to count path components
  completion: fix bugs with slashes in remote names
