That may be so, yet there may be an issue here for someone packaging
Cygwin programs for use as native Windows applications.

That is to say, there could potentially be something here that the 
Cygnal
project could address:

http://www.kylheku.com/cygnal/

Cygnal is an ultra-light fork of the Cygwin DLL that is intended for 
users like Dmitry Katsubo, who run Cygwin programs out of the Windows 
environment directly, after building them in Cygwin.

As I seem to recall, CMD doesn't do anything, period! It passes the 
command line
as one big string. It has to since that's the OS mechanism.

The quoting conventions come from how various run-time libraries deal 
with that
string. An influential convention is that of the MS Visual C run-time 
library;
it behooves other run-times to be compatible with that for consistency 
with
programs whose main() was compiled with MSVC.
