drop array allocations on `html_safe`
For better or worse, anonymous `*` args will allocate arrays. Ideally,
the interpreter would optimize away this allocation. However, given the
number of times we call `html_safe` it seems worth the shedding idealism
and going for performance. This line was the top allocation spot for a
scaffold (and presumably worse on real applications).
