Actually, I do put my functions in .kshrc. I include the typeset also
because I find vi is funny about what it includes in a subshell, and
wasn't defining my ll() function w/o the typeset. As a matter of fact,
most of what is in my .kshrc is there instead of in .profile, not because
I want to maintain compatibility w/ /bin/sh, but because of vi's quirks.

Sorry, of course you're right. I tested his function (calling it cp) to
be sure of the evaluation order, but then my mind short circuited when I
wrote that builtins executed before aliases as well. :-)
