bug#3686: 23.1.50; Sticky mouse-face highlighting


From: Stephen Berman
Subject: bug#3686: 23.1.50; Sticky mouse-face highlighting
Date: Fri, 26 Jun 2009 09:59:54 +0200
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/23.1.50 (gnu/linux)

1. Create the file ~/test.el with this content:

(setq diary-display-function 'diary-fancy-display
      diary-number-of-entries 7)

2. Create the file ~/diary with this content:

Jun 26, 2009 10:00 This is a test
Jun 27, 2009 10:00 This is a test
Jun 28, 2009 10:00 This is a test
Jun 29, 2009 10:00 This is a test

3. emacs -Q -l ~/test.el

4. `M-x diary' pops up a fancy diary buffer with this content (line
numbers added for subsequent reference):

1    Friday, June 26, 2009

3    10:00 This is a test

12   
13   Monday, June 29, 2009
14   =====================
15   10:00 This is a test
16

5. Move the mouse pointer over the fancy diary buffer.
=> As expected, line 3, 7, 11, and 15 have mouse-face highlighting when
   the mouse pointer moves over them.  However, lines 4, 8, and 12 (but
   not 16) also get mouse-face highlighting, and it remains when the
   mouse pointer moves off of those lines.

I suspect this bug is due to this change:

2009-06-22  Chong Yidong  <address@hidden>

        * w32term.c (x_draw_glyph_string): Use the glyph string's width
        rather than its background_width for drawing the overline and
        underline (Bug#489).

        * xterm.c (x_draw_glyph_string): Use the glyph string's width
        rather than its background_width for drawing the overline and
        underline (Bug#489).
        (xg_default_icon_file): New variable.
        (syms_of_xterm): Initialize it to the Emacs SVG icon file.
        (x_bitmap_icon): Under GTK, use xg_default_icon_file.

        * xdisp.c (Qbefore_string, Qafter_string): Add externs.
        (load_overlay_strings): Remove externs.
        (fast_find_position): Function deleted.
        (mouse_face_from_buffer_pos): New function, based on
        fast_find_position.  Correctly handle before-strings,
        display-strings, and after-strings (Bug#1220).
        (note_mouse_highlight): Use mouse_face_from_buffer_pos.

since it does not happen with my previous build before this change, but
I don't have time right now to confirm this by reverting the change.
