sequencer: use repository parameter in short_commit_name()

Instead of just using the_repository, we can take a repository parameter
from the caller. Most of them already have one, and doing so clears up a
few -Wunused-parameter warnings. There are still a few callers which use
the_repository, but this pushes us one small step forward to eventually
getting rid of those.

Note that a few of these functions have a "rev_info" whose "repo"
parameter could probably be used instead of the_repository. I'm leaving
that for further cleanups, as it's not immediately obvious that
revs->repo is always valid, and there's quite a bit of other possible
refactoring here (even getting rid of some "struct repository" arguments
in favor of revs->repo).
