OK, so do I understand you correctly, do you want it to work like
this?

if only --branch is given, use the heads of that branch as a
   collection of revisions to use (call it 'revisions')
if only --revision is given, use that as a collection of revisions to
   use (again, 'revisions')
if both --branch and --revisions were given, use the intersection
   between the branch heads and the revisions and use that as a
   collection of revisions to use

if there are any of the collected revisions that are descendents of
   the current revision, reduce the collection to only those
   descendents.

if the collection holds more than one, alert the user.

you now have one revision to update to.

Cheers,
Richard
