Description of problem:
The format from "cal -3" that I get on April 30, 2007 is wrong.  There are seven
missing spaces between the "30" in April and the "27" in May:
% cal -3

There are 10 spaces instead of 17.

Version-Release number of selected component (if applicable):
% cal -V
cal from util-linux-2.12p
% cat /etc/redhat-release 
Fedora Core release 4 (Stentz)

How reproducible:
Just use "cal -3" (though it may be sensitive to today's date since the inverse
video is the last thing before the formatting problem)


Steps to Reproduce:
1. cal -3
2.
3.
  
Actual results:
     March 2007            April 2007             May 2007

Additional info:
I tried on both rxvt and xterm and gnome-terminal in case the terminal's inverse
video had something to do with it.  Same result on all.  I did it from inside an
emacs shell and May 27 is in the right place, but April 30 doesn't print
properly, but I assume that's an emacs problem.
