    etdump: Fix the file name included in the could not open error message
    
    If only one file is passed, this reads the terminating NULL and so
    prints (null). If multiple files are passed then this always prints the
    second file, which may or may not exist (and will be particularly
    confusing if it does exist since the output will include the dump of the
    second file).
