lynx-dev [PATCH 2.8.4dev.10] size change in OS/2 port

[Ilya Zakharevich]

This patch allows changing size of lynx term at runtime (!mode 110,30;exit).

I hesitated to send it, but now I think that this is the best choice.
Any other way (like sending SIGWINCH to itself) will break lynx running in
an xterm...

Enjoy,
Ilya
