Hmm, this is what I get:
* Dumped revision 3363.
* Dumped revision 3364.
* Dumped revision 3365.
reposurgeon "script nut.lift" "write nut.fi"

Notionally, I like the git-svn idea of having "branch-name at rev", with the latest branch dropping the "@rev" part. With the reposurgeon commit ID format in mind, I could see using an ISO timestamp, but the username is probably not necessary. Since renaming branches is not an O(N) operation, I think that dropping the @rev for the most recent branch could be done in a separate pass.

I still haven't had a chance to really look at the different merge points, but I would not mind just manually entering merge information for now (since we didn't do all that many merges in this repository). Other projects might be better test cases for automatic merge detection.
