Basically, unless you have a proper frame-background-mode, then _all_
the highlighting in Emacs will be fairly screwed up:  a large percentage
of the colors used in Emacs highlighting only look good against the
proper background type.  Attempting to pick "neutral" faces for
everything simply doesn't work -- it's hard enough making things look
good if you _can_ depend on the background type -- and the problem is
even worse on ttys with their limited selection of color and alternate
font styles (basically only bold, and often not even that, works).

So even if we changed the comint prompt to make you happy, the entire
rest of the interface will still look awful.

If you can find a way to detect Putty/rxvt then Emacs could use that
information, but absent that, I don't think there's any choice but user

Bold is already used in comint.  But for the real problem, see above.


In New York, most people don't have cars, so if you want to kill a person, you
have to take the subway to their house.  And sometimes on the way, the train
is delayed and you get impatient, so you have to kill someone on the subway.
