Oh, that's a pity, I was almost ready with v2...

Unfortunately, this makes the general helper function unworkable, of
course.  Though in this particular case it wouldn't matter, because on
Windows daemonize() is basically a noop and 'git gc --auto' remains in
the foreground anyway.

I think we should stick with my initial patch, then.
