This is a very dramatic description of a problem ("can't make heads or
tails", "I have no idea what is meant", etc.), so I'm not sure whether
a simple cross-reference to the documentation of add-hook, which
explains what is meant by "buffer-local" in this case, will solve the
problem.  If it will, doing that is very easy.  In fact, I just did.
