I would like a --count argument to pull (and perhaps any other interactive
command). This would be mainly useful when tracking down failures using binary
chop or batches.
Merging issue1501 in (which also wants get --count).
One thing I didn't understand when I first replied in msg7353 is that changes
--count does something different (it outputs the number of patches).
I guess we could call this --max-count instead, which seems like it'd be
consistent with changes --max-count
