I'm confused: there are any number of revisions that match this definition. You wanted just one. Put it another way: AFAIU, "-r ancestor:" _requires_ a branch specifier. Which branch do you want to specify there? I assumed it was the parent of the current branch. If you want the trunk instead, we could either use http://bzr.savannah.gnu.org/r/emacs/trunk (requires a live connection and Savannah being up) or we could chase the parent pointers until we find a branch whose parent is on Savannah. But it sounds like this is academic: it will be too slow to be a part of the build, because "bzr version-info" is slow.
