Subject: New function unix_get_terminal_size.
X-Git-Url: https://scope-eye.net/git/?a=commitdiff_plain;h=d05fb0d8298f2757b77f5567ada437d304ebd1b8;p=liskon_frotz.git

New function unix_get_terminal_size.

Now startup and resize use the same code for getting the terminal
size (including override support).
