Should mod_dav_svn turn SVN_ERR_FS_LOCK_OWNER_MISMATCH into HTTP_LOCKED?

If I lock a file in a wc using one user ID and then commit that wc using
a different user ID the commit fails, which is the expected behaviour.
Over HTTP I get "500 internal server error" which is not a good error
for something that is a client problem.

We could use "423 locked" instead, would that be sensible from a DAV
point of view?
