preparatory to fixing #7080. Note that mathed uses the same routine, but for a completely different purpose, so I did not rename it there. I have seen no difference in behavior after testing, e.g., opening and exporting Math.lyx, and also re-saving it and looking at the diff. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@38109 a592a061-630c-0410-9148-cb99ea01b6c8
