[darcs-devel] darcs patch: optimize optimize --reorder.

[Eric Y. Kow]

Quite straightforward.  Going in.

For the interested:

The optimize works by removing all patches (since the last checkpoint?),
magically reordering them, and then adding them back in the new order.
Before, we would update the pristine cache along the way, both in
removing the patches, and in adding them back in (add a patch, update
pristine, add a patch, ...).  This is silly because optimize should not
have any net effect on pristine anyway.  Thus the optimisation consists
in _not_ performing the pristine cache updates.
