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.

For the remaining:

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!
