yard-mode's value of eldoc-documentation-function is only useful in 
comments. I'm maintaining another package, which sets a different value 
of eldoc-documentation-function that is only useful outside of comments. 
The two don't mesh.

Ah, good. Never having used `add-function' before, I assumed it wouldn't 
work when the "value at place" is nil, as eldoc-documentation-function 
is, by default.

I guess that means *-functions hooks are going away.
