Re: git-unpack-objects < pack file in repository doesn't work!

It's not a bug, it's an undocumented feature. It should be documented as 
"git-unpack-objects < $pack; rm $pack" is something one would deem correct at 
first glance (luckily I just moved the pack away and did git-fsck-cache).

To write an object, git-unpack-objects ends in

unpack-objects.c:write_object -> sha1_file.c:write_sha1_file:

        /* Normally if we have it in the pack then we do not bother writing
         * it out into .git/objects/??/?{38} file.
         */

This indeed works, so the files aren't unpacked.

Funny, I just did the exact same thing today, scratched my head and
said ``what did I just do!?!?!'' as I had deleted the pack before
discovering that nothing was actually unpacked.  *sigh* At least
it was a clone of the real repository and thus didn't matter to me.

I totally didn't expect that behavior.  But I should have.  It makes
perfect sense.
