Now I've thought about it a bit more, it seems to be the only approach
that will work since the original grob no longer exists if you defer
the calculation (I did say my question might be silly. :)

BTW, I notice there's another (undocumented) key in bound-details
which you're ignoring when the before-line-breaking callback is
called: 'default
