Re: Customize and autoloaded libraries

[Richard Stallman]

Defining `defhook' and changing so many hooks to use it is a large
change.  We have better things to do with our time, and asking users
to change their code is a burden on them.  I am thoroughly against it.

Perhaps there is some way that :type 'hook could cause this other
default value of :initialize.  Is that possible?

If not, perhaps the other solution is best: not merging values, but
making the initialization happen before the add-hook is really done.
That way, we can keep using defcustom with no problem or
inconvenience.
