Comment 6 for bug 131279

I am not convinced the added complexity of internally recording revisions ids for revno-based, plain-text branch references is worth the trouble.

If people refer to a revision by anything than revid, then use uncommit or pull/push --overwrite to change the meaning of what they referred to, things will be confusing anyway. So the simplest, and the closest to what the user did, is the better.

Things are different for bug references found in revision data, or other forms of linking when the revision id is known. This comment only applies to linking to revision by revno from plain text references such as bug comments.
