By the way, I wonder if accidentally identical revisions
(see example for accidental clean merge on revctrl.org)
would get the same revision id in bzr. In git they would.

They won't. The revision id is made up of the committers email address,
a timestamp and a bunch of random data. It wouldn't be hard to switch
using checksums as revids instead, but I don't think there are any plans
in that direction.

The place for timestamp and commiter info is in the revision metadata
(in commit object in git). Not in revision id. Unless you think that
"accidentally the same" doesn't happen...

The revision id isn't parsed by bzr. It's just a unique identifier that
is generated at commit-time and is currently created by concatenating
those three fields. It can be anything you like. The bzr-svn plugin for
example creates revision ids in the form
svn:REVNUM@REPOS_UUID-BRANCHPATH and bzr-git uses git:GITREVID. Nothing
will break if bzr would start using a different format.

Cheers,
