+ and %20 are as far as I know only interchangable in *query strings*,
so having to clone 'git://git.gnome.org/gtk%2B' where you could
previously clone 'git://git.gnome.org/gtk+' is a bug. Git shouldn't be
changing that + to a %20.

I haven't followed why we need to escape + to %20 at all, even in the
query string. E.g. curl(1) doesn't do that before sending requests to
Apache, which can handle either one. The + v.s. %20 duality is always
handled at the server AFAIK.
