My answer is I don't know.  This part of the code is very fragile at the
moment and I don't want anybody changing anything without extensive
run-time testing of all sort of cell contents.  I've experienced painful
debugging where changing small thing like that resulted in very weird
breakage which took me a day to debug.  So, I'm not keen on changing
anything in this area without understanding the risk involved.

I'm working on cleaning up this area to make debugging less painful
