[ale] $PS1 stuff

Thanks to everybody who responded!  

I actually found what I was looking for when I found a little proggie called
"bashprompt".  It's at http://bash.current.nu.  It's just a collection of
shell functions, but it was a little too complicated for my tastes, so I
built a shell function of my own into my bashrc.  I call it bp() (for
bashprompt doh!) :

bp()

clear; echo -e "\n                 Bash Prompt Themes: \n blue, combo, cyan,
elite, elite2, fire, green, \nmagenta, red, redhat, suse, white, yellow,

The kicker for me was getting my fonts sqared away.  I kept on issuing
escape codes that didn't display as promised.  I later found out that I had
to use VGA pcf fonts and nothing else.  I installed sabvga, adjusted my
.Xdefaults, and now it seems to work quite well.  The fonts were why it
wasn't working on bash 1.14.7 before.  Also because you have to use
\[\033[??;??m\] for the ANSI color escapes on pre 2.0 bash builds.  \e alone
won't do it.  (works fine on greater than 2.0 though.)

Thanks to all who pointed me to many and various places for number
conversion.  The ASCII manpage, the ISO_8890_1 man page, and the xfd utility
also.  Going xfd -fn sabvga (or whatever fontname) has been a big help.

Anyway, I feel like I have a workable grasp of this thing now; my first two
prompts are "friendly" and "spiffy" above.  Let me know if you like them,
okay?
