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.
