Not for me to say, but I'd expect unplanned (ie: a bug).

Interesting, an option I haven't used.   If it acts like it says it should,
the only downside should be the appearance of multi-line history entries,
for the command

        while sleep 4
        do
                echo awake
        done

instead of the normal

        while sleep 4; do echo awake; done

in the historu, you get the original, with the newlines embedded
(though it appears some semi-colons are still added), that is, I got

        while sleep 4;
        do
        echo awake
        done

(I didn't really type the indented "echo" as shown above).
That ';' is harmless.   The longer form just makes history entries
occupy more vertical space, and be slightly harder (IMO) to edit,
otherwise there should be no difference.
