Hello,

I've recently switched to org mode as my fundamental mode, and do
almost all of my writing in it now. One issue that I've encountered,
however, is that with a lot of text under a single subheading, when
holding the up arrow key to move point up (running previous-line, found
in global-map), emacs throws the "beginning of buffer" exception (and
rings the bell) before moving point up. I still am able to move up a
line, it's just that the cursor movement when holding down the key is no
longer smooth, and I get a visual warning.

I've found that this only occurs when visual-line-mode is set (I use
global-visual-line-mode). When I turn it off, I get no errors.

I cannot reproduce it. In the following document, starting anywhere in
the paragraph, and holding UP, moves point to the first line.
