It would be good to remove that caveat. It's pretty horrible really.

I don't see much point in fixing just one case (all UIDs the same), even if
that is the most common case. We should fix it properly:

- Find all the different repositories of TARGETs.
- For each repository:
   - Find the HEAD revision of that repository.
   - Update all the TARGETs that are in that repository to that revision number.

Anyone fancy doing that (without making too many extra network round-trips)?

Are there other APIs that have a similar problem?
