svn propedit URL

(I assume there must have been discussion of this before, but I'm
having trouble finding it.)

It would be useful to support "svn propedit" on URLs. The obvious
problem with modifying properties on URLs is accidentally overwriting
somebody else's changes. While this is clearly a problem for propset
and propdel, it's not as big of a deal (in theory) for propedit: svn
could remember the revision of the property being edited, and pass it
through the various layers of propset, and the operation would fail if
it was out of date. This can be implemented with the current RA API;
it just needs a new client API (and 'svn' changes).

I'm specifically proposing the following API change. What do folks
