Greg Lehey b20a21a6c1 Add two new options:
-W is like -A (number of days in the future to consider, but also
   specifies that we don't want special treatment at weekends.
-F changes our notion of "Friday" (the day before the weekend).

Arguably, calendar(1) is broken to have special treatment of weekends
by default, but this method maintains POLA.
