"ksh" is definitely one of them; it has both EMACS-like and "vi"-like
editing modes.  I think "tcsh", which is distributed in the form of
patches to C shell source, is another.  "bash", the Bourne-Again Shell, is
another as well; it's a GNU program, and is Bourne shell compatible.

Another alternative might be Ken Almquist's "atty", which is a user-mode
tty driver that offers similar functionality; it runs a pseudo-tty and
runs your program in that pseudo-tty.  It's available in the
"comp.sources.unix" archive.
