   Bug report for emacs version 18.57, in shell.el. Calling the function
   shell when a shell buffer already exists destroys the markers marking
   the last command typed. This is because make-shell calls shell-mode
   for a buffer which is already in shell mode. I have changed make-shell
   (see diffs below) to only call shell-mode on a new shell buffer, not
   when switching to an already existing one.

There's a simpler fix.  Just check to see if the buffer is already in
shell mode:

    (or (eq 'shell-mode major-mode)
        (shell-mode))
