Ah, understood. I can see that it might get annoying.

This I agree with... we should set the svn:needs-lock property on some
binary files, perhaps some images in www/ or something, at leave it at
that. We could have a pre-lock hook that rejects a lock on anything
that *doesn't* have an svn:needs-lock property already.

I don't think we need to block on teaching mailer.py to send
lock-emails. Yes, it's a nice extra bit of communication. But since
(I believe) all svn developers use reasonable editors, the
svn:needs-lock property isn't in a danger of being accidentally ignored
(hijacked). While it's nice to get an active email saying that you
locked an image file, it's also perfectly fine for me to discover that
fact when I run 'svn lock', no? It doesn't seem like a blocker to me.
svn:needs-lock is one type of communication, mailer.py is a 2nd type of
communication. I don't think we need to have both features in order to
start making basic use of locks.
