I think is is easily missed, and will not inform of the keybinding for
`eldoc-doc-buffer'.  But it's clearly better than nothing for the
strictly-one-line people.

It does not because most of that variable (except for the very special
"truncate-sym-name-if-fit" value) is now handled in eldoc.el.  Modulo
