[PATCH 2/2] http-backend: give a hint that web browser access is not supported

[Jan Engelhardt <jengelh@inai.de>]

Add a paragraph that browsing to http-backend is not something
that should normally be done
 a webserver is configured to unconditionally pass requests
to git-http-backend, without any diversion to a gitweb frontend,
it is helpful to at least be told this.
