Stefan,
Thank you very much for your clarification and your help so far.
I considered doing it the way you described. Unfortunately, most of
the seven (7) missing revisions are for binary files (DLLs and DOCs)
and so I can't reproduce their variations by hand. And since SVN is
storing binary deltas, not entire files, for each commit, I believe I
would have to reproduce them perfectly to get this particular solution
to work.
Any ideas how to get around this or where to go from here?
Thanks,
/eiren
