The `dumb` terminal driver has an optional size specification and trailing linefeed control.
Syntax:
set terminal dumb {[no]feed} {<xsize> <ysize>}
{[no]enhanced}
where <xsize> and <ysize> set the size of the dumb terminals. Default is 79 by 24. The last newline is printed only if `feed` is enabled.
Examples:
set term dumb nofeed
set term dumb 79 49 # VGA screen---why would anyone do that?"
