File::HomeDir is _supposed_ to support overloading of home directories
via $ENV{HOME} at all times (even on Windows, where the HOME variable
doesn't exist).
We may need to add some special casing someone can demonstrate this
not working, perhaps we can ask the XDG for the home directory, and if
the result doesn't match $ENV{HOME} we ignore everything else that XDG
says... (pun totally intended) :)
