Sounds good to me.

Good question... Popularity-wise, the shorter spelling shows up across
quite a few projects on GitHub, but the only spelling of
`BIO_meth_new(BIO_TYPE_NONE | ...)` that I can find is a single place
inside OpenSSL's own test suite -- which also uses the shorter
alternative, in two places. So my vote is BIO_TYPE_SOURCE_SINK; we'll
be in good company.
