patch 7.4.2112

Problem:    getcompletion(.., 'dir') returns a match with trailing "*" when
            there are no matches. (Chdiza)
Solution:   Return an empty list when there are no matches.  Add a trailing
            slash to directories. (Yegappan Lakshmanan)  Add tests for no
            matches. (closes #947)
