From looking at the code I see that login sets the window size
parameters to zero, and then tset sets them for the terminal
if they are zero to start with and are found in the termcap file.
The result of this is that if you change a terminal from 80-column
mode to 132-column mode and run tset, the window parameters stay
at 80 cols and vi continues to wrap around at the 80th column.
The user has to log out and log back in with the changed terminal
mode to get it to work 'properly'.

Does anybody know why it should be this way, and why tset shouldn't
set the window parameters regardless of whether they were found to
be zero?
