It seems like eldoc-mode has some problems (or maybe I'm missing something).

I've just been testing it with an "emacs -Q" session.

For example, write this in the *scratch* buffer:
  (dolist (a b c) d e)
and then move point just before the "a".

The echo area becomes empty. Unless I'm missing something, it should
show the syntax of "dolist":
  (dolist (VAR LIST [RESULT]) BODY...)
with "VAR" highlighted.

The echo area is also empty with point just before "b" and "c".
Similarly, it should show the syntax with "LIST" and "[RESULT]"
highlighted, respectively.

With point just before "d", the echo area shows the syntax but with
"LIST" highlighted, when it should highlight "BODY".
And with point just before "e", the highlighted part is "[RESULT]",
when it should be "BODY" too.

You could do a similar experiment with the expression
  (while a b c)
and move point just before "c".  => the "TEST" part highlighted, when
it should be "BODY".
