Yup, I'll set it to lowercase: they are the types of documents we
generate. That it needs to be in caps in variables is just a naming
convention.

Right. This is a bug. For _HOOKS variables in all package infras, we
exclusively use uppercase. So should we do here, too.

However, as you noticed, this is not correctly handled. I'll fix before
I repsin the series.

Right.

Neither am I. Still, I believe that's the way it is used. For example:
    https://en.wikipedia.org/wiki/Comma#Between_adjectives

Title is unrelated to the subject, but the sentence uses a comma after
"that is".

    http://www.thefreedictionary.com/that+is

Quoting from two places:
    To explain more clearly; in other words: on the first floor, that
    is, the floor at street level.

    When that introduces a relative clause, the clause is usu.
    restrictive, that is, essential to the complete meaning of the
    sentence.

Hmm... Sure thing, we learn a great deal of English on the Buildroot
mailing list. What was the last argument we had some time ago? hehe! :-)

Well, it used to work at one time, but now it does not any more.
As I said above, we want variables to be all uppercase, so the manual is
acurate in what we want; it's just a problem with the implementation,
that is, it is buggy. :-]

/me hides... Muhahaha! :-)
