Hi.

In longlines-mode, showing hard newlines makes the apparent/displayed
point position to "jump" annoinly.  This bug makes longlines-mode with
longlines-show-hard-newlines useless.

How to reproduce.

1) emacs -Q

2) get some text with some long lines (spaces are necessary).

I do this copying "test " and yanking several times, making several
paragraphs (see recent input below).

3) M-x longlines-mode

4) M-x longlines-show-hard-newlines

5) use arrow keys (up and down) to navigate through the text.

Apparently, when point crosses two C-j, the displayed point goes to
upper right corner (blinks there as it does normally) giving the
impression that point is there.  Sometimes it even "recenters" as if
point where elsewhere.  When (real) point leaves 2 C-j, point behaves
normally.

Regards

Miguel Frasson.
