Completion doesn't work

[jaredly]

When I run iocaml -completion, and then type print_e and press tab (to trigger completion), nothing pops up, and in fact the kernel stalls (no subsequent execution requests work, I have to kill the kernel).
When running the ocaml kernel under jupyter, completion requests don't do anything either, although it doesn't stall the kernel.

Looking at the log file (when running from iocaml -completion, it has:

Exception: Ag_oj_run.Error("Line 1:\nMissing record field line")
Dying.

ah, I was missing ocp-index

Lets leave this open, as the kernel shouldn't just crash (in fact the -completion arg should be rejected if ocp-index isn't installed).
