The reason for normalize was to make the code easier to read and
understand.  Every filter must be able to deal with 0 length buckets,
because nobody knows everytime that they will be inserted.  Remember that
just because we have written a core_input_filter, that doesn't mean it
will always be used, it is easy enough for anybody to replace it.  The
easiest way to deal with 0 length buckets is to remove them from the
brigade.  However, you are correct that there are a lot of problems with
just removing them, so we should fix the code instead of hacking around
