I don't see the 5-arg call.  What I see on the current master branch
around like 931 is this:

        ;; Observe the old and the new protocol:
        (cond (;; Old protocol: got string, e-d-strategy is iself the
               ;; origin function, and we output immediately;
               (stringp res)
               (register-doc 0 res nil eldoc-documentation-strategy)

This calls register-doc with 4 arguments, not 5.

Do you have some local changes, per chance?  Or maybe you are not on
the master branch?
