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.
