	* data.c (gpgme_data_read): For GPGME_DATA_TYPE_NONE, return EOF
	instead an error.

	The following changes make it possible to flush an inbound data
	pipe before invoking a command handler:

	* posix-io.c (_gpgme_io_select): Accept new argument NONBLOCK to
	_gpgme_io_select.  Set timeout of 0 if this is set.
	* w32-io.c (_gpgme_io_select): Likewise.
	* io.h: Add new argument NONBLOCK to _gpgme_io_select prototype.
	* wait.c (do_select): Add new argument to _gpgme_io_select
	invocation.
	* rungpg.h (_gpgme_gpg_set_command_handler): Add new argument
	linked_data to prototype.
	* engine.h (_gpgme_engine_set_command_handler): Likewise.
	* engine.c (_gpgme_engine_set_command_handler): Likewise.
	* passphrase.c (_gpgme_passphrase_start): Pass NULL as linked_data
	argument to _gpgme_engine_set_command_handler.
	* rungpg.c (struct gpg_object_s): New members linked_data and
	linked_idx in CMD.
	(_gpgme_gpg_new): Initialize those new members.
	(_gpgme_gpg_set_command_handler): Accept new argument linked_data.
	(build_argv): Handle linked_data in the same hack as cb_data.
	(read_status): If linked_data is in use, flush the pipe before
	activating the command handler.
	* gpgme.h: Add prototypes for gpgme_op_edit_start and
	gpgme_op_edit.

	The next changes export the status codes to the user:

	* decrypt.c (_gpgme_decrypt_status_handler): Likewise, also prefix
	all STATUS_ with GPGME_.
	* delete.c (delete_status_handler): Likewise.
	* decrypt-verify.c (decrypt_verify_status_handler): Likewise.
	* encrypt.c (_gpgme_encrypt_status_handler): Likewise.
	(_gpgme_encrypt_sym_status_handler): Likewise.
	* encrypt-sign.c (encrypt_sign_status_handler): Likewise.
	* engine-gpgsm.c (parse_status): Likewise.
	(gpgsm_status_handler): Likewise.
	(gpgsm_set_recipients): Likewise.
	* export.c (export_status_handler): Likewise.
	* genkey.c (genkey_status_handler): Likewise.
	* import.c (append_xml_impinfo): Likewise.
	(import_status_handler): Likewise.
	* keylist.c (keylist_status_handler): Likewise.
	* passphrase.c (_gpgme_passphrase_status_handler): Likewise.
	(command_handler): Likewise.
	* progress.c (_gpgme_progress_status_handler): Likewise.
	* sign.c (_gpgme_sign_status_handler): Likewise.
	* trustlist.c (trustlist_status_handler): Likewise.
	* verify.c (_gpgme_verify_status_handler): Likewise.
	* gpgme.h (GpgmeEditCb): New type.
	* rungpg.h (GpgStatusCode): Rename and move to ...
	* gpgme.h (GpgmeStatusCode): ... this and here.
	* Makefile.am (status-table.h): Run mkstatus on gpgme.h, not rungpg.h.
	* mkstatus: Prefix STATUS with GPGME_.
	* rungpg.h (GpgStatusHandler, GpgCommandHandler): Change type
	accordingly.
	* ops.h (_gpgme_verify_status_handler,
	_gpgme_decrypt_status_handler, _gpgme_sign_status_handler,
	_gpgme_encrypt_status_handler, _gpgme_passphrase_status_handler,
	_gpgme_progress_status_handler): Likewise.
	* rungpg.c (struct gpg_object_s): Likewise for CMD.code.

	These changes add an edit operation to GPGME:

	* context.h (struct gpgme_context_s): New member RESULT.edit.  *
	ops.h: Add prototype for _gpgme_release_edit_result and
	_gpgme_passphrase_command_handler.
	* passphrase.c (command_handler): Make non-static and rename to ...
	(_gpgme_passphrase_command_handler): ... this.
	(_gpgme_passphrase_start): Use new name for command handler.
	* types.h: Add EditResult type.

	* edit.c: New file.
	* Makefile.am (libgpgme_la_SOURCES): Add edit.c.
	(libgpgme_la_LDADD): Rename to libgpgme_la_LIBADD, and include
	assuan_libobjs.
	(assuan_libobjs): New variable, set this instead
	libgpgme_la_LIBADD.
	* engine.h (_gpgme_engine_op_edit): New prototype.
	* engine.c (_gpgme_engine_op_edit): New function.
	* rungpg.h (_gpgme_gpg_op_edit): New prototype.
	* rungpg.c (_gpgme_gpg_op_edit): New function.
