I made the '-- more --' prompt a separate minor mode, as that seemed
sensible--can't really see any use for the distinction, but better to have it than
try to add it later once we figure out what it's for and then have more
compatibility issues (no pun intended!).
I kept '!' as a major mode as really none of the other modes apply--even though
the function used to return 'n', it's not necessarily true that you will be in
normal mode after an external command finishes. So I'd view that change as a
bugfix not a breaking of compatibility. If you think that's a bad call, it could
be changed to 'n!' I suppose.
