'svnadmin load' only uses revision numbers for calculating offsets so
that copyfrom-revisions work out right. If you have 15 revisions in
your dumpfile, it wouldn't matter what their numbers were, your
repository will still grow by 15 new revisions upon loading that
dumpfile. I have yet to dream up an actual use-case for wanting
--renumber-revs.

See above. If your pre-dump and post-load repositories have
mis-aligned revisions (revision 12 in the one doesn't represent the
same changeset as revision 12 in the other), WCs will get royally
messed up.
