Gary, you've prompted me to spend a minute to bang thick rust off last
century's gleaming awk skills, to hack:

PS1="$(pwd | awk -v FS='/' '{print "+/" $(NF-1) "/" $NF ": "}')"

This produces a slightly (to my eye) enhanced version of the prompt that
OOzy requested:

+/sli_16/src: pwd                   # The prompt is cwd and its parent.
/home/erik/projects/sli_16/src

The "+" is better than ".." for obvious reasons, and shorter than "..."
There's a space following ":"

OOzy, I'm sure that you'll be able to edit out any parts of the new
prompt which you consider a waste of space. :-)

Happy hacking,

Erik
