So, at this moment you can create a branch, so you can easily control which changes
go into the release, yes? Then any subsequent changes on the trunk won't affect the branched
version, and you can control what does go into the branch

So, if the development was occuring on the trunk, merge -r 101:102 and -r 104:105 to the branch will do what you want. Again, this is better control, and it's obvious in the log when changes are going into the release candidate. I'd argue that your release canditate was back at r 102 and not now

The revision number is the revision of the repository, not any single file.

I think the functionality exists to support this example as is, IMHO
