[Remind-Fans] Upgraded to Ubuntu 20.04, got remind 3.3, bunch of new warnings from remind for stuff that worked before

[Dianne Skoll]

Following up on myself.

The reason that:

REM Sun Apr 1 ++2 SATISFY [trigdate() < '2007/01/01'] MSG DST starts

issues a warning, but:

REM Sun Apr 1 ++2 UNTIL 2006-12-31 MSG DST starts

does not, is that in the latter case, Remind can determine unambiguously
that the reminder has indeed expired.  In the former case, all Remind knows
is that for some reason, the SATISFY condition never returned true.  Remind
can't dig into the reasons for that because in general, SATISFY expressions
can be very complex, so it issues a warning.

Regards,

Dianne.
