I have a copy of Wolfgang Rupprecht's ksh enhancements:
shellext	  87-10-12
     W. Rupprecht, <wolfgang@mgm.mit.edu>
     Ksh-like extensions to shell.

Excerpted from his posting:
;This is a ksh-like extention to shell.el.  These extentiions implement
;command history (backwards, forwards, back-search, forward-srearch),
;filename completion, and history printout for an emacs shell window.
;The one glaring difference between this and ksh, is that all of the
;shell-mode commands are bound to the Control-C prefix map. (Eg.
;previous command is C-c C-p).
;
;The full list of shell commands is:
;
;	C-c C-a         shell-beginning-of-line
;	C-c C-c         interrupt-shell-subjob
;	C-c C-d         shell-send-eof
;	C-c C-h         Prefix Command
;	C-c TAB         shell-filename-expand
;	C-c RET         shell-push-input
;	C-c C-n         shell-next-command
;	C-c C-o         kill-output-from-shell
;	C-c C-p         shell-previous-command
;	C-c C-r         shell-history-search-backward
;	C-c C-s         shell-history-search-forward
;	C-c C-u         kill-shell-input
;	C-c C-w         backward-kill-word
;	C-c C-x         Prefix Command
;	C-c C-y         copy-last-shell-input
;	C-c C-z         stop-shell-subjob
;	C-c ESC         Prefix Command
;	C-c C-\         quit-shell-subjob
;	C-c [           show-output-from-shell
;	C-c h           shell-list-history
;
;This is a diff for shell.el(18.49) (to add a few hooks, and some
;personal bug-fixes/hacks) and a file shellext.el, which does the real
;work.
;
;This basic code has been running on 18.26 as well as 18.49, so you
;shouldn't have much trouble, even on older emacses.

I'll be happy to send it out to anyone who provides me with an
adequate address or uunet-based path.
