I guess it is a bug.  The reason it happens is that the "-n" option
essentially adds an infinite delta to each reminder.  That is, you
can think of it as changing:

	REM something MSG foo

to:

	REM something +Inf MSG foo

which always causes the reminder to trigger.  Now the code that processes
triggers is the same as the code that processes IFTRIG, so the IFTRIGs get
a +Inf delta, which makes them always trigger.

It is too hard to fix this, so I will most likely change the documentation
to say that IFTRIG statements can mess up the "-n" mode. :)
