[BUG] turn-on-org-cdlatex

[Rasmus <rasmus@gmx.us>]

Hi,

It would seem there is a bug in turn-on-org-cdlatex whenever _ or ^ is
called.  And perhaps others. 

To reproduce:

bash> emacs -q 

In *scratch*

#+begin_src emacs-lisp
;; adjust the two following lines to your system
(load-file "/usr/share/emacs/site-lisp/auctex/texmathp.el")
(load-file "~/.emacs.d/elpa/cdlatex-4.0/cdlatex.el")
(require 'cdlatex)
(add-hook 'org-mode-hook 'turn-on-org-cdlatex)
(switch-to-buffer "test.org")
#+end_src
Then
  
  M-x org-mode

#+begin_src org
* test
  insert `$' then `x' then `_' then `1', i.e. $x_1$
#+end_src

I get the following backtrace

Debugger entered--Lisp error: (void-variable last-command-char)
  (char-to-string last-command-char)
  (concat (char-to-string last-command-char) "{")
  (string= (buffer-substring (max (point-min) (- (point) 2)) (point)) (concat (char-to-string last-command-char) "{"))
