Could you do me the small favor of spelling my name correctly?

add-hook's doc string clearly states that the HOOK symbol is a
variable, from which you can infer that you can modify it with
set/setq like any other.  The reason users should not be encouraged to
do so is obvious: a hook is a list-valued variable that should be
modified incrementally to limit the scope of the change to what is
intended and not not affect other aspects of the system of which the
user may not be aware.

How does add-hook/remove-hook contribute to more bogus bug reports
than set/setq?

I don't agree.  If a user expects flyspell to work regardless of
whether the buffer is read-only or writeable (i.e. checking the
current word after each command), then disabling it automatically is
clearly wrong (and doesn't allow him/her to control Emacs' behavior).
Leaving it as is at least gives users like you the opportunity to turn
it off.

Ah, the magic 86.8046875 KB buffer size.  :-)
