Ah right! Now I see, thanks!

Will there be a tool to convert an old repository with "fake renames" into
"real renames" (possibly - but not necessarily - withouth having to go through
a full dump/load cycle)? If this tool is not planned / will not exist, the
forward-trace heuristic you speak of (guessing fake renames as real renames)
might be worth it.

Yes. As I already heard complaints about this kind of issues, I can assure they
are really annoying for users :)
