regarding cache or other internal details.

Test that "hg rollback" doesn't restore dirstate to one at the
beginning of the rolled back transaction in not-"parent-gone" case.
invoking pretxncommit hook will cause marking '.hg/dirstate' as a file
to be restored when rolling back, after DirstateTransactionPlan (see wiki
page for detail).
