Comment (by jinmei):

 Another quick question: the change committed in the branch modified
 EncodeNormalizer::operator*(), while the original proposed fix was
 about DecodeNormalizer::operator*().  Could you clarify it?  Is that a
 typo of the original proposed fix, or did you find the original report
 was wrong and the problem was actually in and only in
 EncodeNormalizer?

 In any case, lacking the environment, it's not very clear to me what
 is exactly wrong with the original implementation (calling operator*
 at the end() of the data is wrong of course, but I don't understand
 how that situation happened).  Please explain more details about the
 problem.

 Thanks,
