I'm glad your were able to solve your problem, but do note that your 
method will break if you use a different size default font. Margins are 
specified in terms of characters, and the font you're using happens to 
report a width of 7 and a height of 11. It'll likely break if you use a 
different terminal (probably because of a different default font), or if 
you add a title. Of course, good enough is often good enough :)
