/** This routine implements a rather snazzy idea suggested by Warren
Carithers of the Rochester Institute of Technology that allows
mail to contain entries formatted in a manner that will allow direct
copying into a users calendar program.
Never able to leave good-enough alone, I've extended this idea to a
further one - the knowledge of a different type of calendar program
too. Specifically, the current message can contain either of;
-> Mon 04/21 1:00p meet with chairman candidate
or
- >April 21
-
- 1:00 pm: Meet with Chairman Candidate
-
The first type will have the leading '->' removed and all subsequent
white space, creating a simple one-line entry in the users calendar
file. The second type will remove the '-' and the leading white
spaces and leave everything else intact (that is, the file in the
second example would be appended with ">April 21" followed by a
blank line, the 1:00 pm meeting info, and another blank line.
The file to include this in is either the default as defined in the
sysdefs.h file (see CALENDAR_FILE) or a filename contained in the
users ".elmrc" file, "calendar= <filename>".
