There's a fun issue with this code that I'll fix, but thought was informative to send a mail about. Because the graph verification happens in the main "git gc" process, as opposed to everything else via external commands, so all this progress output gets written to .git/gc.log. Then next time we do a "gc --auto" we vomit out a couple of KB of progress bar output at the user, since spot that the gc.log isn't empty.
