* sign.c (gpgsm_sign): Ditto.
* base64.c (base64_reader_cb): Reset the linelen when we need to
skip the line and adjusted test; I somehow forgot about DeMorgan.
* server.c (cmd_encrypt,cmd_decrypt,cmd_sign,cmd_verify)
(cmd_import): Close the FDs on success.
(close_message_fd): New.
(input_notify): Setting autodetect_encoding to 0 after initializing
it to 0 is pretty pointless. Easy to fix.
