[PATCH 0/3] Fixes to mh/rebase-fixup

This patch series contains fixes to the mh/rebase-fixup patch series
as suggested by reviewers on the mailing list.

Since the mh/rebase-fixup patch series is already in "next", I have
written these fixup patches against "next".  I hope that is OK.

The third patch removes the attempt to use one-shot export of
variables in do_with_author(), as the "$@" command that it calls might
be a shell function.  This issue was discussed on the mailing list
[1].  This change has the side effect that the GIT_AUTHOR_* variables
remain exported after do_with_author() returns, but I don't think that
this is a problem in the context of git-rebase--interactive.sh.
However, additional review would be welcome here.
