cygport: Suppressing the creation of *.cygwin.patch

[Ken Brown]

I've started using here documents in my .cygport files to create 
postinstall scripts when necessary.  But then cygport creates an 
unnecessary .cygwin.patch file.  I can prevent that with

   cp -R ${C} ${S}/../../origsrc/${SRC_DIR}

Is there a better way to deal with this situation?  Or should cygport 
have a RESTRICT option for it?
