Ksh and csh have two different philosophies as far as command history
editing goes.  They both have good and bad points.

What I miss from the csh is the ability to say:
	``I want words 0 thru 5 and 7 thru 11.''
		!:0-5 !:7-11
or
	``I want everything exactly the same, but change the string `foo'
	  for `bar' in the last word.''
		!:0- !$:gs/foo/bar/

These changes might look trivial, but when your command line has wrapped
around (or scrolled left) a few times it gets to be a drag.  Even worse is

	``I want to apply command `foo' to the last word of the previous
	  command.''

		foo !$

Note, I'm not saying these can't be done with ksh, but I'm saying that I'd
rather write !$, however cryptic, than go through an unending sequence of
keystrokes to accomplish the exact same thing.

Perhaps having both would be the best.
