I don't understand what you are saying here.  The last sentence is
incorrect, as evidenced by the following:

  (expand-file-name "~/.emacs" "/tmp")
   => "/home/eliz/.emacs"

IOW, "~/.emacs" is indeed treated by Emacs as an absolute file name,
but expand-file-name does NOT return "~/.emacs" unchanged.

So please explain what exactly is the problem you see here, and in
particular what issues that problem causes in your case.

Thanks.
