Subject: Fix vertical cursor motion among many images
X-Git-Tag: emacs-28.0.90~3772
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=1a6c7c10951ce6dadfdab36ad6ff6f679526828f;p=emacs.git

Fix vertical cursor motion among many images

* src/xdisp.c (move_it_in_display_line_to): Consider it
MOVE_POS_MATCH_OR_ZV if we are just after an image, stretch, or
display string, and the position matches exactly.  This is needed
when one image follows another at TO_CHARPOS.  (Bug#46464)
