I have an implementation on a branch if anyone wants to test...

They work in 99% of cases.  Where they break is this, using the new
Remind from the branch:

       # Specify the year
       OMIT Jan 1 [$Uy] THROUGH Jan 31 [$Uy]
       REM 1 Feb -1 MSG Trigger #1

       CLEAR-OMIT-CONTEXT
       # Don't specify the year
       OMIT Jan 1 THROUGH Jan 31
       REM 1 Feb -1 MSG Trigger #2

If we run this file with:  remind -dt example.rem 1 Dec 2022 we get different
results for the two triggers:

        $ ./remind -dt /tmp/example.rem 1 Dec 2022
        /tmp/example.rem(3): Trig = Tuesday, 31 January, 2023
        /tmp/example.rem(8): Trig = Saturday, 31 December, 2022

Admittedly, this example is a little contrived.

Dianne.
