No, the sentence was "I have no idea if this is correct from the ISDN
point of view because we drop the end of the buffer." I don't think
there are piles of people to care about ISDN much nowadays. So we can
close that it is correct to drop the rest of the buffer. In a hope that
+M is not followed by text longer than 50-or-so chars.

There is nothing more to fix. (Well, there is, but not in this context.)
