[Pkg-shadow-devel] [PATCH] su: also preserve COLORTERM

[Mike Frysinger]

From: Sebastian Rick Rijkers <srrijkers at gmail.com>

For some terminals COLORTERM seems to be the only way for checking for that
specific terminal. For instance, gnome-terminal sets its TERM as "xterm" but
its COLORTERM as "gnome-terminal". The COLORTERM variable is also of use when
running GNU screen since it sets TERM to "screen" but doesn't touch COLORTERM.

Currently su -l only preserves the TERM variable, COLORTERM is unset. This
simple patch makes su -l preserve the COLORTERM environment variable as well.
