Subject: [PATCH] Run "resizewin -z" from the default shell profile files. This
 makes the terminal work properly out of the box when logging over a serial
 line, which is quite important for the user experience on boards like
 Raspberry Pi.  It doesn't affect cases where the terminal size is already
 non-zero, such as SSH or vt(4) sessions.

Note that this doesn't handle a scenario pointed out by rgrimes@:
when the terminal is resized after login, the terminal size won't
get updated even after logging out and back in.
