Naw. Here's the plans: Every time we return from a shell command and
place the cursor to rest at a prompt, we take a back towards the
beginning of line to remember what this prompt looked like.... no, how
about we remember a character offset from beginning of file... no,
what if the user took out a chunk of the file... ah yes: we just "set
a mark" in a private mark list... then the ^C^P's will jump to the
exact previous "prompting" locations, no matter if we were uing all of
sh, bc, dc, mail, or whatever... or perhaps set comint-previous-prompt
directly from PS1... but today's PS1 is loaded with
metacharacters... ok never mind.
