[LyX/master] Add conversion routine for format 612.

[Richard Kimberly Heck]

commit 4966da6864df0f53a12fe1453ce749452431df88
Author: Richard Kimberly Heck <rikiheck at lyx.org>
Date:   Mon Dec 5 14:45:40 2022 -0500

    Add conversion routine for format 612.
    
    I forgot that this is needed, because the new parameter is written to
    the file no matter its value.
    
    Also, fix two typos in the reversion routine.
