The gpg child process exiting does not necessarily mean that we've ready

2003-04-15  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-gpg-context.c (gpg_verify): The gpg child process exiting
	does not necessarily mean that we've ready everything that we can
	from its pipes, so don't use gpg_ctx_op_exited() as a loop-exit
	condition. If for some reason the gpg child process does exit (due
	to an error), gpg_ctx_op_step() will eventually fail (as soon as
	it has finished reading any data in the pipes) and cause the loop
	to be terminated anyway. This fixes truncation of the gpg --verify
	stderr output that Evolution displays as the "validity report"
	(for lack of a better description).
	(gpg_ctx_op_step): Removed some debugging printf's
	(gpg_ctx_get_diagnostics): Use a bitfield to decide if we've
	already flushed the diagnostics stream, much simpler (plus we have
	plenty of bits to spare so might as well use them).
	(gpg_ctx_new): Fixed another logic bug which determined whether or
	not we should convert the gpg output from the locale charset into
	UTF-8.
