[babel] problem removing label from src

["\"Martin G. Skjæveland\"" <martige@ifi.uio.no>]

Hi all,

I use the -r -l option for source blocks to change the format of labels. 
This works in org-mode without org-babel, but this does not fully work 
with org-babel (and I really like org-babel, so that's a shame :) )

The following

--------------start---------
#+begin_src xml -n -r -l "<!--(ref:%s)-->"
   <test>
     <important/> <!--(ref:imp)-->
   </test>
#+end_src

Line no. [[(imp)]] is important!
--------------end---------

gives me

1:  <test>
2:    <important/> <!---->
3:  </test>
    Line no. 2 is important!


The label and reference works, but the label is not fully removed. 
<!----> is left behind.

Thanks!
Martin
