Reverting the "offending commit" is a bad idea, because the code it
corrected was obviously hiding bugs, which would hit others who treat
BIO filters correctly (i.e. actually check if there's any pending
input or output).

Simply put, the zlib BIO filter doesn't behave correctly in this
regard.  Corrective PR here: https://github.com/openssl/openssl/pull/9876

Cheers,
