From e144e1b67fa7bda9dfd361529279db6818d2002e Mon Sep 17 00:00:00 2001
From: "Richard M. Stallman" <rms@gnu.org>
Date: Thu, 6 Jun 1996 15:27:03 +0000
Subject: (bright_bg): New function, enables bright background colors.
 (dos_set_window_size): Move code to `bright_bg'. (IT_set_terminal_modes):
 Enable bright background colors. (IT_set_frame_parameters): Don't mask bright
 color bit in background colors.  Record colors on `termscript' file.
 (internal_terminal_init): Enable bright background colors.  Fix default
 colors setting from $EMACSCOLORS.
