Subject: [PATCH] Corrected an apparently long-standing error with the
 triggered rules (such as widespacing or directional surround) that will cause
 the rule to be triggered without a cause due to a failure to reset the error
 count from a previous triggered rule (the condition of failure is much more
 rare than this explanation makes it sound, which is why it went undiscovered
 for so long).
