Don't immediately prompt for a passwd after receiving the NEED_PASSPHRASE

2003-12-11  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-gpg-context.c (gpg_ctx_parse_status): Don't immediately
	prompt for a passwd after receiving the NEED_PASSPHRASE status
	message. Instead, parse the userid that gpg needs a passwd for and
	store it on our context. Wait for a GET_HIDDEN status message
	before prompting, this way if the user has their gpg configured to
	use gpg-agent, the user won't get 2 passwd prompts.
	(gpg_sign): Fixed to not free a gpg context that we have not
	allocated (could happen in a fail case).
