I guess my assumption was that the "winshell" parameter would be used to determine
when a Cygwin process is called from a non-Cygwin process and that it would be more
appropriate to use standard Windows command line processing (as limiting as it may
be) in that case. Once in the Cygwin environment, calls from one process to another
should obviously process command lines according to Unix shell rules.
