That would rise the number of differences between loclists and
qflists to a grand total of two :) (the other difference being that
loclists are per window, while qflists are global). Not sure adding
subtle differences between the two a few years after their creation
would be such a great idea... Also, I believe the Vim tradition is
that backwards compatibility always trumps making sense.
