As we prepare to handle S/MIME-encrypted PKCS#7 EnvelopedData (which is not multipart), we don't want to be limited to passing only GMimeMultipartEncrypted MIME parts to _notmuch_crypto_decrypt. There is no functional change here, just a matter of adjusting how we pass arguments internally. Signed-off-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>
