Refactor the `evil-ex' Elisp check into a new function, `evil-ex--elisp-p', since it is used twice now. Add an `eldoc' function that calls `elisp-eldoc-documentation-function' if in an Elisp expression and if the former is available.
`make-variable-buffer-local' should not be used in Elisp and makes the argument permanently buffer-local. Use `make-local-variable' + `set' instead, maing `evil-ex-setup' not set `completion-at-point-functions' as permanently buffer-local and allowing to remove `with-no-warnings'.
For Emacs < 24.4, which does not have `add-function' and `remove-function', use `add-to-list' + `eldoc-documentation-functions' instead.
