Thanks for the clarification, I didn't realize that, obviously.

The manual sometimes calls these values being symbols "hook", and
sometimes "hook variable".

Ok, so, these arguments of `add-hook' and `remove-hook' must be
variables (symbols) representing a hook.

My proposal to rename the `hook' argument to `hook-var' would still be
reasonable.  Sure, there is no error in the current naming.  But it
would not be false, and clearer than now for people that didn't yet
realize this part of the nomenclature, like me.

Please decide yourself - I just have the feeling that many people
stumble at that point and don't know if they must use a quote before the
hook variable or not.

OTOH, if there are good reasons to reject my proposal, please close this
report.


Thanks,

Michael
