	* glib/gutils.c (g_path_get_dirname): Fix Win32 behaviour in some
	cases where a drive letter is present. For 'a:' or 'a:foo', return
	'a:.'. This is mostly just for consistency with the behaviour
	without a drive letter. But very important is to for 'a:\foo' or
	'a:\', return 'a:\', and not 'a:'. (Ditto for forward slashes
	instead of backslashes.) (#137316)

	* tests/dirname-test.c (main): More complete testing on
	Win32. If a test fails, include expected and actual result in
	error message.
