Why, one doesn't have to be a "cygpath" guru at all! A little judicious
application of sed, and you can turn a space-separated path into a
colon-separated one. Which reduces the problem to the one already
solved... ;-)
Seriously, though, you could use something like
	"`/bin/ls /cdv/D/goodies/babe*.jpg | cygpath -w -f -`"
as the argument. This should expand all the files.
It would certainly be a good idea to add multiple filename capability to
cygpath. If I have time over the next week, I'll submit a patch.
