    Fix file-tests.el on MS-Windows
    
    * test/lisp/files-tests.el
    (files-tests-file-name-non-special-start-file-process): On
    MS-Windows, wait till the process dies before returning from
    the files-tests--with-temp-non-special macro, to ensure the
    temporary directory is successfully deleted.
