[PATCH] provide a Git user-manual man page

This is a resend of my original patch ($gman/240486), which disappeared without comment. I've cc'd those who have touched the User-Manual in the last year for comment on the provision of this access mechanism.

The Git User Manual is formatted as a doc book, rather than as a man page so isn't directly accessible via the usual 'git help <guide>' command.

This patch provides a simple man page with onward links to the true User-Manual.

The man page is based directly on a very cut down version of the git(1) page.

This patch is based on 1.9.0 master.
