It's not the case that only "propset" could clobber other people's changes. So
can "svn rm URL" and "svn mv URL URL" already, and propdel, import, merge, etc.
also could if we were to allow them to. So that's not the sole reason we
haven't supported propset on URLs.

I don't see anything special about "propset" compared to the other commands.
