Thanks for elaboration.  I guess your spacing is too wild(?)
so I changed (only spacing or tabbing) your patch as follows.

And I have a question.

+    # This time it's not necessary. But if we ever add
+    # defaults again, we have to fish out double occurences

Is this really true?  I suspect there might be a user who 
already did "dpkg-reconfigure tetex-bin" and setted french 
and/or ngerman and so double occurence could be there.
