Re: Git-commits mailing list feed.

It may sound a little weird, but we could actually store the signature in 
the inode/filename. GPG signatures seem to be around 80 bytes of ASC, 
thats well below MAXPATH and should work even if your repository is 
somewhere/deep/in/your/filesystem/hierarchy. 

1. Signed objects are named sha1-sig (sig is a 80 character signature 
here, not the three letters sig).

2. To make sure we can find objects without their signature, there is 
   always a soft link sha1 -> sha1-sig (fsck can check this and create 
   missing links).

3. To find a signature, just follow the link and look at the real name.

4. Files can be distributed without signature (content is unchanged) and
   you can sign them in your local tree with your own signature, 
   effectively throwing my signature away.

The only limitation is that each object can only be signed by one person. 
On the other hand, this might not be a limitation at all. If I create a 
file, I sign it. Nobody else. Same goes for trees and commits that I 
create. You can sign your own commit object when you merge my stuff, and 
then push that commit object out (along with your co-signature).
