Yeah, but color doesn't work everywhere.  Ever used terminals with
a white background?  Horrendous.

Plus, I (almost) never login as root.

When I first started using this code, I didn't use the bash/zsh
special escapes to print the username, host, or directory because
pdksh didn't support them.  It turned out to be a blessing in
disguise when I tried to to use the same prompt at work, where they
use some decade-old systems.  All those fancy color/underline/bold
codes don't work there either.
