Fix part of bug #13011 with display of lines that have a box face.
src/xdisp.c (handle_face_prop): Fix logic of computing it->start_of_box_run_p. (append_space_for_newline): If the glyph row is R2L, reset the iterator's end_of_box_run_p flag before prepending the space glyph. (extend_face_to_end_of_line): If the glyph row is R2L, reset the iterator's start_of_box_run_p flag before prepending the stretch. (append_glyph, produce_image_glyph, append_composite_glyph) (append_stretch_glyph, append_glyphless_glyph): Reverse the left_box_line_p and right_box_line_p flags of the glyph for R2L glyph rows.
