svn mv REPOS_URL/macos-resource-forks REPOS_URL/macos-rsrc

doesn't break the repository either. Clients that aren't aware of
resource forks won't see any different. Clients that are aware of
resource forks should be written to detect a possible problem (e.g.
missing macos-resource-forks directory) and should be able to
ignore resource forks (and let the user correct the repository)
until things are fixed.

This is a bit similar to "svn remove REPOS_URL/trunk", where you
can't do anything useful until some user restores the trunk.
