Right, perhaps we should clarify this while the opportunity is ripe
for style.lua(9) into something more like "80 columns are preferred,
wrapping may occur much earlier than 80 columns." I blindly followed
it here because we hadn't discussed any exception to it previously,
but I think we're more likely in Lua to run into scenarios where the
current guideline just isn't appropriate.
