There was additional output, but I thought it was meaningless since I
think it shouldn't try to complete at all when the current word is
empty.

Yes, with this, it works fast. However, it doesn't use all history
anymore for regular completion. The search is done only on the last 100
items of the history. I would prefer to have complete completion when
there is at least one character in the current word and nothing when
not. I don't think people are interested to expand the empty word with
the content of the history.

In the meantime, this is a good workaround. Thanks!
