[feature request] git-daemon http connection filtering of client types

Hey folks,

When I checked for false positives in my spam this morning, I spotted an interesting malformed img link at the top of a spam message.

So, apparently git-daemon's http features are being used by spammers. In most cases, spam filters will correctly identify this junk.

I wonder if there is a better way... In my mental sandbox, git-daemon http could have a set of deny/allow rules for incoming connection client types. e.g.:

git: allow git-http: allow thunderbird: deny outlook express: replace linked file with rickroll.jpg

and so on.. An out-of-the-box install probably should default to allow all to keep backward compatibility.

While I'd love a chance to hack something out, I sadly doubt I'll ever have the time for it. Perhaps there is a student hacker looking for a project.

Cheers! -phil

p.s. appologies to anyone who now has Astley's song stuck in their head. This was not intentional.
