That about wraps it up for serv_calendar.c

Seeing this code has really brought me back to the upstairs room
in my old house where I wrote most of it back in 2002-2003.  I can
see the sunlight coming in the windows, the color of the carpet,
the little alcove where the computer was, the cat sleeping on top
of the big CRT monitor.

Hopefully the stuff I need to add to it now will be straightforward
since it looks like I really took my time and commented it heavily.
It looks pretty clean, especially now that I've reformatted it with
the new screen width an C99 comments.  It does seem a bit WET though.
