ksh for the suns.

Well, *mostly* like "ksh", unless they've added support for "ksh"'s
EMACS-mode ^O character (the one that lets you conveniently recall an
entire multi-line control construct and reexecute it, after possibly
editing some or all of the lines in it).  If it doesn't do that, it's
not enough like "ksh" for me....

Ken Almquist's "atty" *does* support that function.  It's an
"alternative tty driver" - basically, a program that uses pseudo-ttys
and takes over the function of the simple-minded "editor" in the tty
driver.  He also has "ash", an "alternative shell" that supports a
basically S5R2-or-later-flavored shell with job control, but doesn't
support history, leaving that up to "atty".
