Correct - _my_ tree is behind Linus' tree.  Therefore, if you have Linus'
latest tree, you *already* have all of Linus' commits in *your* tree and
git should not be fetching any of Linus' commits from me.

The 550 errors are because the unpacked objects don't exist; they're
already inside one of Linus' pack files which you should already have.

That's the point - you should already have these git IDs (the ones you
explicitly refer to) so there should be no reason for git to even
consider fetching them via http or ftp.
