Oh, right, i is signed. I reviewed this right after reviewing some
unsigned comparisons and had the wrong thought process engaged...
And now I recall that when I'd read this before in previous revisions
I had had the same impulse at least once, but those times I noticed
it was signed before sending comments. Anyway, sorry for the noise.
