I can.  I already had a look into this.  The command line handling in
Cygwin is different from the command line handling in MingW or, FWIW,
VC++ CLI applications.

The question is if we really should align the rules how a native
command line is evaluated by a Cygwin process should be aligned
to Windows rules or not.

There are three arguments to consider:

- Using Windows/MingW rules lowers the surprise.

- Changing the rules at all breaks backward compatibility.

- Why shouldn't Cygwin applications use their own rules which seem
  more appropriate for a POSIX application?

Btw., if you want the same result as for the noncygchild, just quote:

  $ cygchild "a\"b\"c"
