GRIPE:
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.
NEW FEATURE REQUEST:
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.
