updated for version 7.3.264
Problem:    When the current directory name contains wildcard characters, such
            as "foo[with]bar", the tags file can't be found.  (Jeremy
            Erickson)
Solution:   When searching for matching files also match without expanding
            wildcards.  This is a bit of a hack.
