Depends on what you are running thru - you have layers - in that test case you
ran from cmd, so cmd parsing has to be first taken into account, before passing
the resulting command line to bash, where Cygwin will construct a POSIX argument
list from cmd output, and pass that to bash then script.sh.
Try your testing using my script.sh shown earlier, and call bash with -vx
options for debugging output.
