Re: http://cygwin.com/cygwin-ug-net/using-cygwinenv.html

  (no)glob[:ignorecase] - if set, command line arguments containing
  UNIX-style file wildcard characters (brackets, question mark, asterisk,
  escaped with \) are expanded into lists of files that match those
  wildcards.  This is applicable only to programs running from a DOS
  command line prompt.  Default is set.

There was no DOS command line prompt in anything below.
