Good idea.

That's the 42€ question.

BTW, as I meanwhile realize, max-width is also set to 8.  Max-width is
computed a few lines below space-width.  From reading the code, I'd say
that is most likely when space-width has already been 8 there.  Which
leaves only a small window for overwriting.

Or both have been overwritten.  Many things are possible.  ATM, it's
just my gut telling me it's not overwritten.
