I want *both* real history editing, as in ksh's real vi mode and not
tcsh's abortion of the same, as well as expression history (!f:s/x/b),
which may be ugly, but is quite convenient.  But ksh won't do asynch job
notification, key rebinding, or spelling correction, so I'm stuck with an
abomination of a shell.
