Unfortunately I was over-optimistic (and misled by the comments), so no
reimplementations from me :-(. See the other message I just sent.

Ah, that's good to hear. I couldn't understand what the mod_dav_svn code
was doing, but if it's only for old clients, that's great! [Since that
means I can safely ignore it, essentially, localising the change to just
svn_repos_begin_report(), which is a lot easier to test.]

The latter sounds like an excellent idea, though I'm not _entirely_
sure what the concise function you're talking about would look like
(though that's probably because I don't understand what mod_dav_svn is
doing with it).
