Subject: Fix cursor display at EOL before extended face
X-Git-Tag: emacs-27.0.90~545
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=1265e947113efe335139038c89c280db480994af;p=emacs.git

Fix cursor display at EOL before extended face

* src/xdisp.c (extend_face_to_end_of_line): Make sure the
character position of the stretch glyph inserted to extend the
face is zero, as various other parts of the display code rely
on that.  (Bug#38330)
