Comment 15 for bug 1016643

I looked into g10/keyserver.c a bit and had hoped that import_keys_stream() there could be used to test if the fingerprints match the expected fingerprints, but it seems that the fpr/fpr_len arguments will only set to the fingerprint of the last key imported. So I need to check something else, maybe reading the spawn->fromchild stream into a tmp IOBUF, verify that and pass it on afterwards.
