Subject: Fix alt- -> console switching
Date: Tue, 4 Nov 2003 17:30:31 +0100	[thread overview]
Message-ID: <20031104163031.GB220@elf.ucw.cz> (raw)

Hi!

Take vesafb, do cat /etc/termcap, while it is printing press alt and
right arrow twice. Oops, it only goes one console to the right.

Problem is that if console is already being switched and you press
alt- ->, fg_console is still old one and second alt- -> is basically
lost. Here's a fix.
