Greg Anders 055a332133 Only print extra newlines for multi-line prompts (#6179)
Corrects #6110

BSD `seq` produces a down-counting sequence when the second argument is
smaller than the first, e.g.:

    $ seq 2 1
    2
    1
    $

While GNU `seq` produces no output at all:

    $ seq 2 1
    $

To accommodate for this behavior, only run `seq` when we are sure that
the second argument is greater than or equal to the first (in this case,
the second argument `line_count` should be greater than 1).
