Use the liberal file matching to continue file listing/searches

If the user didn't supply a wildcard, only a single file (the first file
matching the liberal file pattern) would ever be listed in the file
listing/searches, even when multiple files in the directory matched the
liberal file matching pattern. This is not a new bug.
