Koma-letter bug: backaddress option not included in latex export

Koma-letter bug: backaddress option not included in latex export

[James Harkins]

I believe I've found a bug in ox-koma-letter.el. Org-mode version 8.2 
(release_8.2-2-g18c7c4 @ /home/dlm/share/org-mode.git/lisp/)

Accepted values for the "backaddress" option are "t" or "nil."

If the option is "t," then the export contains a line 
"\KOMAoption{backaddress}{true}."

If the option is nil, I would expect a line 
"\KOMAoption{backaddress}{false}" but *the line is omitted*. So, LaTeX 
prints the back address anyway, even though the option is explicitly set to 
disable the back address.

I think the problem is here:

   (let ((with-backaddress (plist-get info :with-backaddress))
	 (with-backaddress-set (plist-get info 
:with-backaddress-changed-in-buffer-p))
..
      (when with-backaddress-set
	(format "\\KOMAoption{backaddress}{%s}\n" (if with-backaddress "true" 
"false")))

Somehow, when backaddress is nil, with-backaddress-set must be false, 
causing the line not to be generated.

**Update**: Same problem with #+OPTIONS: foldmarks. Possibly all the 
options are broken.

ECM (the simple example at [1], with one #+OPTIONS line added):

Change it to backaddress:t and you'll see the difference.
