[Eli Zaretskii]

branch: emacs-29
commit 4f0121f8dbe2ca0ec8fe2831353f01782e5e6b9d
Author: Eli Zaretskii <eliz@gnu.org>

    Avoid assertion violations in displaying under 'outline-minor-mode'
    
    * src/xdisp.c (init_from_display_pos): Initialize BYTEPOS
    correctly, since 'init_iterator' no longer computes it from
    CHARPOS as needed.  This fixes a change made on Mar 13, 2013.
    (Bug#71194)
