* Strip pseudomerges: Rewrite the current branch so it contains no
pseudomerges, turning ...B3 into ...p-A-1-2-B3. (This should
- make a note, in your .git/ somewhere, of the latest pseudomerge to
- be deleted.)

* Cleanup branch: Reorganise the current branch so that the debian/
changes come first, turning -p-A-1-2-B3 into ...p-A-B-1-2-3.
* New upstream rebase: Start rebasing onto a new upstream version,
- turning ...#...p-A-B-1-2-3 into ...#'.A-B-p'-1-2. This would be a
- wrapper around git-rebase, which prepares p' and then tries to

- doesn't appear in your commit list.

and B is undesirable. We want the debian/ files to be non-rebasing
so we can `git log' and get the packaging history.)
* Record pseudomerge. This is like "committing" your patch queue.

- should probably check that this is consistent with what we see in
- debian/changelog, but that is not a sufficient check.)

Maybe some of these operations should automatically edit
