I don't know if short description of `http.receivepack`, suitable for
a reference documentation, tells a new user how to configure web server
for pushes.

With `http.receivepack` unset git (git-http-backed?) will refuse
unauthenthicated pushes but allow authenthicated ones (though it doesn't
handle authorization).  This makes it easy to configure web server for
fetches (read-only) access via smart HTTP (and you can make it
bulletproof by refusing pushes at all with `http.receivepack` false,
isn't it?).

But in this case (`http.receivepack` unset - the default) web server
must be configured to request authorization for both steps of push:
requesting references (for coming up with what
repositories have in common), i.e.

  GET ...?service=git-receive-pack

and actual sending of data and updating refs...

  POST .../git-receive-pack

though only second part is actually writing.

With `http.receivepack` set to true git (git-http-backend?) allows
anonymous pushes, and it is responsibility of web server configuration
to deny unauthorized pushes... but it is sufficient to do it only for
writes i.e.

  POST .../git-receive-pack

[Now to translate it to manpage or users-manual contents...]

P.S. Do I understand it correctly that `http.receivepack` is
three-state: true (allow all), unset (allow authenthicated) and false
(deny all)?

P.P.S. It would be better to accept both patches; I don't know when
I would be able to test Apache config; I remember that I had problems
with it...
