    Cygwin: __wscollate_range_cmp: fix incorrect comment
    The comment that the first arg must be the pattern was added
    during development, before it turned out that __wscollate_range_cmp
    can be implemented in an order independent way.
    Better explain why this function uses pointers to strings.
