Right.  But any technical arguments?

What's the difference between solving this in Lisp, which you
would accept, and solving this in C+Lisp?  It's a two line change
like a zillion others just one of the lines happens to be
a single assignment in C.

I can offer to maintain this feature, or the whole display_mode_element
& friends.  Any other grey-hair inducing outstanding bugs (apart from this
one I've found).
