Presently, if you do
emacs -q --no-site-file
(require 'checkdoc)
M-x eldoc-mode
then eldoc will print "nil: Checkdoc Minor Mode Menu" when it has
nothing to say.
One fix is for `eldoc-get-var-docstring' to only return the
documentation if sym is non-nil (see below). Before making the change
I would like to check that it isn't hiding a greater problem, so
please holler if it shouldn't be installed.
