** line-spacing and (recenter -1)

(recenter -1) does not show point at the bottom of the window
if line-spacing is set to positive integer.
Start emacs -Q, and evaluate below:
(progn
(setq line-spacing 1)
(dotimes (i (window-height))
(insert "\n" (int-to-string i)))
(recenter -1))
Then, point is displayed at the center of the window.
But point should be displayed at the bottom of the window like Emacs-21.3.
** scroll-preserve-screen-position doesn't work with a header-line-format

There seems to be an off-by-one error triggered by using a header line
together with scroll-preserve-screen-position. The symptom: instead of
staying in the same position on the screen when scrolling, the cursor
moves one screen line down each time the buffer is scrolled. Put
another way: repeatedly typing C-v M-v or using a mouse scroll wheel to
scroll up and down causes the cursor to migrate slowly down the screen
instead of staying put as it should.
To reproduce:
emacs -q --no-site-file
(setq scroll-preserve-screen-position t)
(setq header-line-format "")
C-v M-v C-v M-v C-v M-v etc.
** line-spacing and garbage in fringe

Start emacs -Q and evaluate below with C-xC-e:
(let ((lines 2)
(spacing 1))
(setq line-spacing spacing
indicate-buffer-boundaries t)
(insert (make-string (window-height) ?\n))
(goto-char (point-min))
(message (make-string (* (window-width) lines) ?.))
(scroll-up 1))
then, garbage is displayed in right fringe.
Above code reproduces this bug with
(frame-parameter nil 'font)
=> "-Adobe-Courier-Medium-R-Normal--12-120-75-75-M-70-ISO8859-1"
If you use different font, you may need different value of
`lines' and/or `spacing'.
** Mouse-face overlay bleeds into header line
From: Stephen Berman <Stephen.Berman@gmx.net>

Mouse-face overlays bleed into the header line when the beginning of
the overlay is above (point-min). To reproduce:
1. Start Emacs with -q -no-site-file.
2. In *scratch* eval
(progn (setq ov (make-overlay 66 92))
(overlay-put ov 'mouse-face 'highlight)
(setq header-line-format "test"))
3. Drag the mouse over the string "evaluation.\n;; If you want" and
notice the highlighting of only this string.
4. Now click on the down arrow in the scroll bar until the line
beginning ";; If you want" is directly below the header line.
5. Drag the mouse over ";; If you want" and notice that not only it
but also the header line are highlighted.
