The cdr of help-split-fundoc return nil as expected for functions, CL-style
function, but always nil for macros even if they are documented.

Thus the docstring seem wrong, as it say it return nil if not
documented, which is wrong because it return a one arg list
in this case.

I had expected documentation has the same behavior for functions,
CL-style functions, and macros.

And it seem describe-function-1 is a long function that have to deal
with these inconveniences.
