To reproduce this bug:

Start Emacs -Q (testing with mainline build dated Jan 29):

Paste the following:

——snip
(global-hl-line-mode)
(setq visual-order-cursor-movement t)
(visual-line-mode)

 asdasd
——snap

Note that “ asdasd” has a space at the beginning, and it needs to be the last line of the buffer.
Evaluate the first three expressions, place the text cursor at the end of the buffer (that is, after “asd”).

The line should be highlighted.  Now press `left’ (or do M-x left-char).

Point will jump to the beginning of the line.
Expected behavior is that it would move by just one char.

HL Line Mode, the Mother Of All Evil...

Fixed in trunk revision 116701.

Does this mean "Aquamacs without customizations" has
visual-order-cursor-movement set to t?  If so, I think it's not a good
idea at all: that variable is user-level customization, it shouldn't
be forced on the users.
