But that function is fast! Compared to doing the actual completion, the 
time it takes to `(funcall hookfun)' should be negligible:

ELISP> (js2-time (setq ocap (with-current-buffer "*Inferior Octave*" 
(octave-completion-at-point))))
0.0
ELISP> (js2-time (with-current-buffer "*Inferior Octave*" (funcall (nth 
2 ocap) "a" nil t)))
0.0055
