Dear Martin:

Problem Solved:

If we ever meet, I will owe you many beers of your choice. You put
your finger right on the problem!

I didn't accidentally do that. I did it on purpose!  I got the idea
from the Sweavel.sty approach that Frank Harrell suggested
(http://biostat.mc.vanderbilt.edu/wiki/Main/SweaveTemplate), which I
have found makes more beautiful output than the Verbatim based Sweave.
You can feast your eyes:

http://pj.freefaculty.org/R/SummerCamp2011/lectures/07-plotting1.pdf

I have mainly used that because it makes nicer looking shades and
symbols like ~ and <-, but in adapting the example he provided, I
obliterated the prompt as well.

I never imagined that making the blank prompt would kill Emacs-ESS.
