>From time immemorial, in the pick man page, the definitions of -after and
-before have been at best ambiguous and at worst wrong.

Here is my stab at a correct definition:

     The only messages considered will be those for which the relevant date
     field exists, has a valid format, and defines a date that is
     chronologically strictly after {before} the date specified.

This assumes that the field occurs at most once. What happens if there is more
than one occurrence is above my pay grade.


Particularly, for use in connection with sortm, there ought to be a
straightforward way of selecting precisely those messages for which a validly
formated, relevant date field exists and has a valid format, or if you prefer
those not having a validly formatted, relevant date field.

Something like

  -before today -or -after today -or -after yesterday

is not straightforward.
