[Emacs-orgmode] org and calc-embedded

[Leon]

Dear Carsten,

I found that org-mode doesn't play well with calc-embedded mode.

For example,

Suppose we have the following formula in org file:

$ ln(ln(x)) $

Now move the cursor to the formula and type 'C-x * e' (activate 
calc-embedded mode). An error occurs: 

,---- | Debugger entered--Lisp error: (error "$'s not allowed in 
this context") |   signal(error ("$'s not allowed in this 
context")) |   error("$'s not allowed in this context") | 
calc-do-embedded(nil nil nil nil) |   calc-embedded(nil) | 
call-interactively(calc-embedded) |   calc-do-dispatch(nil) | 
calc-dispatch(nil) |   call-interactively(calc-dispatch) `----  If 
us \( \) there is not error, but the outcome is still not right. 

Same formula in LaTeX-mode:

$ ln(ln(x)) $  =>  $ \ln\left( \ln{x} \right) $  =>  $ 
\frac{1}{\ln{x} x} $
             (i)                               (ii)
Type:
   (i)  C-x * e
   (ii) adx RET

To exit embedded mode: C-x * e

NB:
This is tested in calc 2.1 in emacs 23. In calc 2.02 'C-x *' is 
replaced with 'M-#'.

Thanks for your time.
