Cool. We definitely should support at least that much.
(although we always want to know when a redirect occurs, even if Neon might
 handle it automatically)

Well, we really ought to push redirect information back at RA's caller. We
don't want the user to check out /A/B/C, have it redirected to /D, yet the
/A/B/C gets stored into .svn/entries. We'd end up doing the redirects all
the time.

Absolutely. Unlike CVS, it means that we can actually move a repository,
leave a little redirect on the server, and not worry about clients need to
rejigger everything they do.

The tricky part will be telling the app "<that> is now located <here>" and
having it do something smart. Especially if <that> is a whole directory and
everything needs to get shifted recursively.

(think: RA callback table)

Oh. If the redirect is "temporary" then we don't store it back into the
'entries' field. If the redirect is "permanent", then we *do* store it.
(301 is permanent, 302 is temporary)
