[PATCH] git-add: Add support for --, documentation, and test.

[Carl Worth <cworth@cworth.org>]

[-- Attachment #1: Type: text/plain, Size: 1885 bytes --]

This adds support to git-add to allow the common -- to separate
command-line options and file names. It adds documentation and a new
git-add test case as well.
