Repost from another account. vger.kernel.org seems not
to like postings from my other alias (which goes through
yahoo).

Argh, thanks a lot!  Should have read the man page better. OTOH,
I expect 'git commit --allow-empty' being needed, but 'git rebase --keep-empty'
comes somewhat as a surprise - I wasn't expecting git rebase to commit
each in turn,
but of course that's what it does.
