	* encrypt.c (_gpgme_encrypt_sym_status_handler): New function.
	(gpgme_op_encrypt_start): New variable SYMMETRIC, set it if RECP
	is null, and if it is set, use _gpgme_encrypt_sym_status_handler
	as status handler and run _gpgme_passphrase_start.
	* rungpg.c (_gpgme_gpg_op_encrypt): If RECP is zero, do symmetric
	encryption.
	* engine-gpgsm.c (_gpgme_gpgsm_op_encrypt): If RECP is zero,
	return error value.

	* rungpg.c (_gpgme_gpg_op_verify): Add "--" argument.
