I think it's in shell-mode to facilitate interacting with the command
while it is running -- for example, using C-c C-c to sent SIGINT, and
also just typing into STDIN.

So we're talking about switching the major-mode at the point the command
exits, which seems like it could cause frustration -- imagine the
command finishes up just while you're typing into the buffer and you
happen to type 'g' ...

Thinking more, I think my C-c C-r solution is the one I prefer; anyone
else in favour of that?
