Like other people I have done some experiments with local repositories
and there is a thing that bothers me: While, by default, `git push' to
some other git repo succeeds only if this would not change the history
of what is already in that repo, there is apparently no such safeguard
against rewriting history in an upstream bzr repo (and pushing to
a bound branch instead does not quite work).

The stuff below corresponds to "NOTE ABOUT FAST-FORWARDS" in
git-push(1).

[1 /tmp]$ bzr init trunk
Created a standalone tree (format: 2a)
[2 /tmp]$ (cd trunk && touch foo && bzr add $_ && bzr commit -m X && bzr log --line)
adding foo
Committing to: /tmp/trunk/
added foo
Committed revision 1.
