This is great if your in an environment with just bitmapped windowing
terminals.  At our site most of the people are hooked up with plain
vt100 compatibles, and don't use windowing.  We had a problem with
people getting lines that rows and columns set wrong in the terminal
driver.  To get everything right, we added a -w switch to tset that
set the rows and columns in the driver to be in agreement with the
termcap.  Those people that don't use windowing and have a tset -wQ in
their .login after the TERM variable is set.
