[PATCH] www: support `+' in inbox names

`+' already seemed to works for IMAP mailboxes and NNTP newsgroup
names and git-config doesn't complain, either.  So allow it as
the path components of WWW URLs so projects like `libstdc++' can
use it.

 There should be better test coverage for this at some point,
 but I suppose this is good enough for now as I'm hacking on
 a more interesting part of this project :>
