Ah, I found it! <Phew> this makes me less worried that I had some
failure in my testing. I believe that upstream things weren't a
problem because of commit d03eba99f5bf ("minmax: allow
min()/max()/clamp() if the arguments have the same signedness.").
...so at least what's landed isn't actually broken upstream, just
downstream. It still feels reasonable to change this to "size_t",
though.
