With latest trunk, the (non-automated) redisplay testsuite is failing in
Test 2. Here is a simplified recipe:
emacs -Q
Insert the following:
(let ((opoint (point))
overlay)
(insert "XXX")
(setq overlay (make-overlay opoint (point)))
(overlay-put overlay 'display "XXX")
(overlay-put overlay 'mouse-face 'highlight))
M-x eval-buffer RET
Move the mouse over the XXX that was inserted.
Result: multiple lines are highlighted, from the end of the first buffer
line to the end of the display string.
Expected result (works in Emacs 23): only the XXX is highlighted.
In GNU Emacs 24.0.92.9 (x86_64-unknown-linux-gnu, GTK+ Version 3.2.0)
of 2012-01-09 on furball
Windowing system distributor `The X.Org Foundation', version 11.0.11004000
configured using `configure '--with-x-toolkit=gtk3' 'CFLAGS=-g''

Did this work with Emacs 24 at some recent time (or ever), i.e. do you
remember this working for you past Emacs 23? If it did, it will allow
me to consider only the latest changes.
TIA

I think I fixed this (trunk revision 106827), but please test,
including any variations on this theme you can come up with. The
bidi-aware mouse highlight is tricky business, especially when display
strings are involved.

Thanks for the very quick fix.
This specific case is indeed fixed, but there is still a failing corner
case in the redisplay testsuite. Load test/redisplay-testsuite.el, do
M-x test-redisplay, and go to the very last case in Test 2.
When the mouse is over the XXX, the highlight only extends to the end of
the text, whereas it's expected to go to the end of the line. This is
the case where there's an overlay with "XXX\n" as the display string and
a mouse face.

I will look into it, but (compatibility with Emacs 23 aside) how
important is it to have the entire display line come up in mouse color
in this case? I could make an argument that what we do in Emacs 24 is
actually better, since the newline is not shown on display as any
tangible glyph.
IOW, are there practical use cases where this difference matters?

Fixed (trunk revision 106848).
