This has come up before, but the discussion was inconclusive (IIRC)
because of 2 reasons:

  . revno is not unique: two different branches can have the same
    revno for two very different code bases

  . revision-id, an alternative method of specifying a revision, _is_
    unique, but it's long and a mouthful:

            address@hidden

In general, a bugfix should appear in the ChangeLog files with the bug
number, so you should be able to track bugfxes that way.
