master 1265e94: Fix cursor display at EOL before extended face

[Eli Zaretskii]

branch: master
commit 1265e947113efe335139038c89c280db480994af
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>

    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)
