Bug#747664: julia--get-object breaks because of mapcan

[Martin Maechler]

Thank you Dirk et al.

Hmm, I had added

(eval-when-compile
  (require 'cl)); in Emacs <= 23.x for (mapcan .)

need 'cl  at least in emacs 23.4
------------------------------------------------------------------------
(too late for 13.09-x)
already.

Unfortunately,  [TAB] completion has been completely broken in
*julia* buffers for me, so I now can no longer test if the
(eval-when-compile ....)  is sufficient.

A simple  (require 'cl)  gives a warning during compilation :

ess-julia.el:42:1:Warning: cl package required at runtime

and that's why I (assume I) used the  (eval-when-compile ...) clause.

ESS corers: Any idea why  [TAB] completion fails in  *julia*,
e.g. after

xyz = 1:10

xy[TAB]

nothing happens, but a message   "no completion on ."
