Yep, I finished analyzing the problem.
There are 2-3 unconventional branches like:
r12345: A /app/version3
r12346: A /app/version3/feature1 (copy from /app/version2/feature1)
r12347: A /app/version3/feature2 (copy from /app/version2/feature2)
(Instead of a simple A /app/version3 (copy from /app/version2)
I' ll dump/load up to revision 12344, commit a proper copy, stuff 2-3 dummy revs to keep the
same revision numbers,
and load the remaining after. This should go fine without too much trouble, while keeping
and maybe not invalidating working copies (I hope).

Indeed. That's not what we want !

Of course, but it's tedious and error prone. We'll only use that if we can't find a better
solution which properly tracks the mergeinfos.
