Ok, that makes a lot of sense ;). I'll write a decent log msg when
I commit it.

Hrmm... Ok, I'll see if I can identify the callers that use STRICT...

And one final comment: there is a little buglet in the patch in
svn_wc_statuses (it returns when there is _no_ error). I've already
fixed that locally, but since it is a one line diff with the patch
I'm not reposting the entire patch.
