Heh. You didn't notice the same change in the merge-tree conversion that 
you already accepted ;)

Yeah, any usage messages will now run after setup for the commands that do 
the whole RUN_SETUP thing. That's pack-redundant, unpack-file, mktag, 
merge-index and merge-tree. So they'll now report "Not a git repository" 
before they report invalid arguments.
