The first patch has already been Acked by spearce.

The second patch uses a consistent "if..." convention throughout the
completion script.

The third patch improves how the __git_ps1 works when (a) the CWD is a
git dir and (b) when the CWD has a .git but no .git/HEAD.

The fourth patch fixes unbound variable errors by replacing $__vars with
${__var-}s.

Ted Pavlic (4):
  completion: For consistency, changed "git rev-parse" to __gitdir
    calls.
  completion: Use consistent if [...] convention. No test.
  completion: Better __git_ps1 support when not in working directory
  completion: More fixes to prevent unbound variable errors.
