Subject: Fix bug #11094 with cursor display on display string after invisible text.
X-Git-Tag: emacs-24.2.90~471^2~368^2~6
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=70f4d9736b7aa878f54530523c281e9db67bf778;p=emacs.git

Fix bug #11094 with cursor display on display string after invisible text.

 src/xdisp.c (set_cursor_from_row): If the display string appears in
 the buffer at position that is closer to point than the position
 after the display string, display the cursor on the first glyph of
 the display string.  Fixes cursor display when a 'display' text
 property immediately follows invisible text.
