    Avoid out of boundary read access
    
    If the environment variable HOME is empty, XauFileName triggers an
    out of boundary read access (name[1]). If HOME consists of a single
    character relative path, the output becomes unexpected, because
    "HOME=a" leads to "a.Xauthority" instead of "a/.Xauthority". Granted,
    a relative HOME path leads to trouble in general, the code should
    properly return "a/.Xauthority" nonetheless.
