I was wrong about the second one (in comment #1 of the bug). It does not
work, either because <edit>'s meant for 4 fonts are applied to all other
fonts as well.

So, at the moment, the only way to achieve what I want I know of  is to use
the old expression and ignore the warning.  It'd be great if there's a way
to do the same without a warning.

Thanks.
