While looking at /usr/bin/calendar in order to checkout the above fix I
noticed a curious line:

		if (/usr/lib/calendar $y/calendar)

Now /usr/lib/calendar is supposed to create a 'sed' script used to find
specific dates in one's calendar file.  I'm not sure that it's exit status
is well defined and I'm not sure what it will do with the argument.
Shouldn't the line be:

		if test -f $y/calendar			?

Is /usr/lib/calendar doing something that's not documented here such as
testing the existence of it's argument?  Just curious.
