   You've *still* got the spelling errors in there. This is a symptom
of the fundamental reason that your reputation is appalling -- you are
sloppy in your work. You miss (or ignore) details, even small easy
ones like fixing up the capitalisation of NULL and the spelling on the
same line. This sloppiness extends to not understanding the code
you're trying to change, not thinking it through, not compiling it
before it goes out, not testing it properly before it goes out.

   Concentrate on the details. There are lots of details, and you need
to get them *all* right. If someone like Valdis says "you need to fix
this, this and this", fix *everything*. Print out the email, use a
highlighter pen to indicate everything that needs fixing. Put a tick
by every item when you've dealt with it. Don't even *think* about
posting a new revision unless you've got a tick next to every single
highlighter mark.

   If someone asks you a question, like "what happens if the condition
in $line_number is true?", this is intended to make you stop and
think. The questions are leading ones, and are trying to make you see
for yourself why there is a problem in your code. The way things are
at the moment, if you look at one of those questions, and answer it,
and the answer *isn't* "<this> bad thing will happen", then you've
missed the point of the question, and you need to look at it harder.
Not answering the question is not an option at this point.

   Hugo.
