Yes.

The documentation of `next-line' function now says:

    If the variable `line-move-visual' is non-nil, this command moves
    by display lines.  Otherwise, it moves by buffer lines, without
    taking variable-width characters or continued lines into account.

It kills ``buffer lines''.  To kill a single display line one can move
the point to the start of that line with the arrows, select the display
line with `S-<down>' or `C-SPC S-C-n' and kill the display line with
`C-w' as usual.
