This problem was introduced when we upgraded to a newer version of
glob().  We're using a fairly recent version of this routine from
FreeBSD bug, AFAICT, it has a bug which disallows quoting characters.

I've checked in a very simple fix for this and am generating a new
snapshot.

Thanks for the test case.  You actually can see the failing behavior by
running cygwin's echo from a windows command line.
