LGTM.
I note that there is no doc update, and I think that is correct, since
we never previously documented that NaN wasn't allowed. The new
behaviour is what one would have expected, given that we do document
that NaN values compare as greater than all non-NaN values.
It could even be argued that this is a bug fix, but the lack of prior
complaints justifies not back-patching.
