Ok, I'm not that familiar with the RCS format, but couldn't this
algorithm catch 97% of the affected files?
- Grab content from rev 1.1 of each file and build MD5 sum
- files whose rev 1.1 is the same have probably been repocopied
- the point in time, where file A is no longer comitted to, and file B
has the first commit which is not also in file A, that's when the copy
I think tools like fromcvs/tohg do a pretty good job at capturing
