* plaintext.c (handle_plaintext): Don't try and create a zero-length filename when using --use-embedded-filename with input that has no filename (clearsigned or message generated from a pipe). * encode.c (encode_simple, encode_crypt), progress.c (handle_progress), sign.c (write_plaintext_packet): Fix a few inconsistent calls (NULL filename means a pipe here, so don't bother to check it twice).
