[PATCH 3/4] completion: fix branch.autosetup(merge|rebase)

[Ramkumar Ramachandra <artagnon@gmail.com>]

When attempting to complete

  $ git config branch.auto<TAB>

'autosetupmerge' and 'autosetuprebase' don't come up. This is because
"$cur" is matched with "branch.*" and a list of branches are
completed. Add 'autosetup(merge|rebase)' to the list of branches using
__gitcomp_2 ().

Also take care to not complete

  $ git config branch.autosetupmerge.<TAB>
  $ git config branch.autosetuprebase.<TAB>

with the usual branch.<name>. candidates.
