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 at REPOS_UUID-BRANCHPATH and bzr-git uses git:GITREVID. Nothing
will break if bzr would start using a different format.
