updated for version 7.3.507
Problem:    When exiting with unsaved changes, selecting an existing file in
            the file dialog, there is no dialog to ask whether the existing
            file should be overwritten. (Felipe G. Nievinski)
Solution:   Call check_overwrite() before writing. (Christian Brabandt)
