Make more not immediately exit on a short file, if the -e option is

Make more not immediately exit on a short file, if the -e option is
given.  This makes more -e basically usable at all when your termcap
entry supports an alternate screen buffer (like xterm-r6).

I wonder whether we should make more -e the default.  Oure more seems
to be the only one on the world with this funny behaviour.
