Re: Colorized Prompts Problem

I do like to use a colorized promt to show my running jobs and whether my AWS creds are in the environment, but I usually use the built in PS2 rather than create insanely long lines. It took a while to develop that habit, though, but it works better. You can of course break lines arbitrarily with a "\"

The bash manpage suggests enclosing the non-printing escape sequences
inside \[ and \]. This is not 100% effective, but it helps.
