Subject: [PATCH] git-shell: Add 'git-upload-archive' to allowed commands.

From: Erik Broes <[email-masked]>

This allows for example gitosis to allow use of 'git archive --remote' in a
controlled environment.

There were some questions on IRC raising (valid) concerns about security.
If there is a dangling commit on the remote end and any user would know
or guess the SHA, it could be retrieved where git-upload-pack will not
allow so.

We were unable to find out if this was the original reason git-shell was
never extended with git-upload-archive functionality or if it was a simple
oversight. If it was the reason I'm not sure there is an easy way out.
