[PATCH v5 17/28] http-backend: reword some documentation

["Shawn O. Pearce" <spearce@spearce.org>]

From: Mark Lodato <lodatom@gmail.com>

Clarify some of the git-http-backend documentation, particularly:

* In the Description, state that smart/dumb HTTP fetch and smart HTTP
  push are supported, state that authenticated clients allow push, and
  remove the note that this is only suited for read-only updates.

* At the start of Examples, state explicitly what URL is mapping to what
  location on disk.

 -----------
 A simple CGI program to serve the contents of a Git repository to Git
 clients accessing the repository over http:// and https:// protocols.
+The program supports clients fetching using both the smart HTTP protcol
+and the backwards-compatible dumb HTTP protocol, as well as clients
+pushing using the smart HTTP protocol.
 
 By default, only the `upload-pack` service is enabled, which serves
 'git-fetch-pack' and 'git-ls-remote' clients, which are invoked from
-'git-fetch', 'git-pull', and 'git-clone'.
-
-This is ideally suited for read-only updates, i.e., pulling from
-git repositories.

+clients, which is invoked from 'git-push'.
