Log Message:
-----------
Minor efficiency improvements in keeping track of trigger deferred
status. In particular, I see no reason for deferredTriggerCheckState
to make an explicit entry to note that a particular trigger has its
default state --- that just clutters a list that should normally be
empty or very short. I have plans to revise this module much more
heavily, but this is a simple separable improvement.
