Emacs creates emacs.d/ as root when using sudo

[Jeffrey Walton]

Hi Everyone,

I think this is unexpected behavior:

    $ sudo apt-get install emacs-nox
    $ sudo emacs /etc/default/motd-news
    $ ls -Al ~ | grep emacs
    $ drwx------  2 root    root     4096 Jul  1 13:56 .emacs.d

Then, when I use emacs as non-sudo, I am nagged with:

    Warning (initialization): Unable to access `user-emacs-directory'
(~/.emacs.d/)

I think emacs should be creating files in user's $HOME as $SUDO_USER,
not root. Or, emacs should be creating .emacs.d/ in /root, not user's
$HOME.
