No, it actually runs "repack -d -l -A", which behaves fine. I even
tested it to make sure.

BTW, the "gc.auto" setting is really annoying at low levels (I set
gc.auto to 1 for testing). For efficiency, it looks at only one
hashed object directory, and then assumes the other 255 contain roughly
the same number of objects. But you get bad sampling error when you have
fewer than 256 objects. I don't think it is worth caring about, though.
It doesn't seem very sane to set gc.auto to something so low.
