[BZ #3996]

2007-02-14  Jakub Jelinek  <jakub@redhat.com>
	[BZ #3996]
	* posix/glob.c (attribute_hidden): Define if not defined.
	(glob): Unescape dirname, filename or username when needed and not
	GLOB_NOESCAPE.  Handle \/ correctly.  Handle GLOB_MARK if filename
	is NULL.  Handle unescaped [ in pattern without closing ].
	Don't pass GLOB_CHECK down to recursive glob for directories.
	(__glob_pattern_type): New function.
	(__glob_pattern_p): Implement using __glob_pattern_type.
	(glob_in_dir): Handle GLOB_NOCHECK patterns containing no meta
	characters and backslashes if not GLOB_NOESCAPE or unterminated [.
	Remove unreachable code.
	* posix/globtest.sh: Add a couple of new tests.
