Create implicits does not work in Emacs mode

[ysalmon]

When using UTop in Emacs, the -implicit-bindings option seems to have no effect.

On discuss.ocaml.org, it was pointed out that uTop uses a different function when processing in emacs mode, that does not refer to get_create_implicits :

utop/src/lib/uTop_main.ml

Line 1078 in 595002e

let phrase = rewrite phrase in

But they do not know why.
