[PATCH 08/21] completion: fix most spots not respecting 'git --git-dir=<path>'

The completion script already respects the path to the repository specified on the command line most of the time, here we add the necessary '--git-dir=$(__gitdir)' options to most of the places where git was executed without it. The exceptions where said option is not added are the git invocations:

  - in __git_refs() which are non-trivial and will be the subject of
    the following patch,
  - getting the list of git commands, merge strategies and archive
    formats, because these are independent from the repository and
    thus don't need it, and
  - the 'git rev-parse --git-dir' in __gitdir() itself.
