	I'll be damrned!  It works--I've used the zsh for almost 20
	years; it's a ksh clone++.  How, may I ask, does this work?
	(I've seen ksh chopping from the RHS; I wrote a short C util to
	axe any part of a string, but have never seen  *this* voodoo.
	LOL++)

	In any event, merci infiniement!

	PS: this will save my rsync scripts too.
