[PATCH v2] Use reflog in 'pull --rebase . foo'

[Martin von Zweigbergk <martin.von.zweigbergk@gmail.com>]

Since c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), "git pull --rebase" has used the reflog to try to
rebase from the old upstream onto the new upstream.

Make this work if the local repository is explicitly passed on the
command line as in 'git pull --rebase . foo'.

Changes since v1: Removed some stuff that I should not have included in
the first place. (Thanks Santi and Andreas.)
