Of course it doesn't behave the same (otherwise, why bother changing
it): "I'm pretty sure surrounding the regexp in \(?:..\) will break no
code at all" doesn't mean that such code can't exist, but that I expect
such code not to exist in the wild (or if it exists, it *suffers* from
the current behavior rather than benefitting from it).
