I was thinking back to a conversation (maybe here) about polluting errno
by setting it *at all* in functions that should only set h_errno.  So, I
flagged a change in whether or not errno was set.  I don't know if that
rule applies in this case, but we should at least know if it does or
not, and say so, so we don't unintentionally make things worse.
