	$_ is almost what you are looking for; it is supposed to be set for
any command to the full name of that command.  if you use it as you use 
CURRENT_CMD above, however, you get something like this:

(astaroth/1)~: precmd() { echo "Just did:$_" }
Just did:precmd
(astaroth/2)~: preexec() { echo "Ready to do:$_" }
Just did:preexec
(astaroth/3)~: ls
Ready to do:preexec
appconfig    Mail         News         public_html  working
bin          mail         news         src          www
docs         misc         nohup.out    tmp
Just did:ls
(astaroth/4)~: 

	i could never figure out why it acts that way, though, so i've
never really used it.
