Do this:

	PS1="amdahl!!krs "    # TWO !'s

The extra space at the end makes long prompts easier on the eye.  If
you don't want it, you don't need the "'s.

The two-! feature is (to the best of my knowledge) undocumented.  It
was a lucky guess on my part.  Any comments, Dave (congrats on the DMTS)?
