	C-e goes to the wrong place in whitespace-mode when the end of line
	is shown
Date: Wed, 23 Nov 2011 08:41:49 -0500

Enable the whitespace-mode which shows a ``$'' at the end of each line.
if a line is one letter shorter than the buffer's width (which means the
``$'' from the whitespace-mode is at the very right of the buffer) and
when the next line is not empty (or maybe when this is not the last
line), C-e in this line will go to the end of next line rather than the
end of this line. (Well, I can see the reason might be emacs take the
fake ``$'' as a real character or sth like this.)

P.S. a seperate but maybe relevant bug in whitespace mode, linum-mode
sometimes doesn't show the line number of some lines (not exactly sure when.)

Thank you.

Also found in trunk; seems to be an issue with `vertical-motion'.

Fixed in revision 106517 on the trunk.

(It was a much more fundamental problem, one that had to do with
starting display on a newline that comes from a display vector.)
