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.
