Surprising indeed. I wish I'd known about this earlier dealing with
some #apache questions about mod_userdir inflexibility.

Given that this is rather surprising behaviour (repetition of effort
in a modular server), I'd suggest maybe also pointing out that with
behaviour is independent of mod_userdir even being loaded:

When the substitution string begins with a string resembling "/~user"
(via explicit text or backreferences), mod_rewrite performs home
directory expansion. This behaviour is independent of mod_userdir
being loaded or configured.
