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

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

From: David Mandelberg <david@mandelberg.org>

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<Tab>

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'

Signed-off-by: David Mandelberg <david@mandelberg.org>
