From: Cornelius Weig <cornelius.weig@xxxxxxxxxxx>
The function __git_complete_revlist_file understands how to complete a
path such as 'topic:ref<TAB>'. In that case, the revision (topic) and
the path component (ref) are both part of the same word. However,
some cases require that the revision is specified elsewhere than the
current word for completion, such as 'git checkout topic ref<TAB>'.
In order to allow callers to specify the revision, extract a utility
function to complete paths from a tree-ish object. The utility will be
used later to implement path completion for git-checkout.
