ANSI Color Escapes in $PS1.. heh.

["Ryan King" <rking@duke-energy.com>]

Just how stupid an idea did I have when I did this:

$PS1="[\e[31m\h\e[m:\e[34m\u\e[m:\e[31m\w\$\e[m]"

in my /etc/profile?

It looks really nifty until I try to do commands that wrap around, in which
case the first line returns, but keeps going on the current spot.

The real disaster, however, occurs when I get into the command buffer...
each time I hit the left arrow, it smears about half the command up a line.

Does bash figure its wraps like so?:

if ( length($PS1) + length($input) > $screen_width ){ print "\n"; }

Because if so, I understand why it is doing what it's doing.

I'm mainly curious, but it makes the whole command-line experience easier
for my newbie eyes when the prompt is in color.
