No color prompt in color capable terminal

[Victor Engmark]

The default .bashrc doesn't enable the color prompt, even though `ls --color=yes` shows colors. The following code is in the default .bashrc:
case "$TERM" in
xterm-color)
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
    ;;
*)
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
    ;;
esac

I propose to change this to the following:
if [ $COLORTERM -o "$TERM" == 'xterm-color' ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi

hmm, maybe a matter of taste; I don't like colored prompts ;-)

Mathias, the proposal is not primarily to force color on those who don't want it, but basically to make the code run as the original coder intended. Specifically, it will look at the COLORTERM variable as well as TERM, which will make it work in gnome-terminal. See also bug 103929. I imagine (and hope!) that there is a way to disable COLORTERM if you don't want color prompts. In any event, I believe this is a proposal for the skel bashrc, which power users routinely override anyway.
