Oops. Fortunately this is not likely to cause trouble in practice, I
can't imagine an extension peeking into 'raw_buf' and friends. But yeah,
we should do something at least on HEAD. +1 on your patch; I'll commit
that unless someone has better ideas.

On REL_17_STABLE, we should probably adjust the comment to warn that
'raw_buf' and friends can move depending on USE_OPENSSL.
