Emacs -Q
M-x about-emacs
M-: (set-frame-parameter nil 'height 25)
[important: this sets the frame so that the line "GNU and Freedom" is half-visible.\
M-x global-hl-line-mode

press <down> repeatedly, until we're on the "GNU and Freedom" line.  The line "Absence of Warranty" should now be visible at the bottom of the window.

Now press <down> once more.  This will NOT advance the cursor, but scroll the buffer up by just a pixel or two.
I am attaching two screenshots showing before and after.

I would expect it to scroll a full line and actually advance my point.

The recipe above applies to Emacs 24, but I can see it with a 23 branch build, too.


Interestingly, this does not reproduce when using `hl-line-mode' instead of `global-hl-line-mode', but I also don't see line-by-line scrolling then.

This problem may or may not be the same as bug#6264.  One difference in this report is 
that the point actually does not move here, while in #6264 the point still seems to move.  But that may just be a matter of setup.
