As I stated in another mail, the arguments to a cygwin program are not
globbed unless an unquoted wildcard character is seen.  Cygwin does
collapse a quoted backslash to a backslash, however.  It also leaves
single backslashes, that do not quote anything "special", alone.

I don't see this as being too inconsistent.  We can't emulate UNIX
behavior 100% because backslashes do mean something to Windows.

It is in the winsup sources.  Grep for 'glob'.
