	** Fix for bug #263236

	* mail.error.xml: New message "ask-delete-vfolder-msg".
	* em-folder-view.c: (emfv_delete_msg_response),
	(emfv_popup_delete): When deleting from vFolder, ask if really want
	to and warn about deleting in a real folder too.
	* evolution-mail.schemas.in: New option
	"/apps/evolution/mail/prompts/delete_in_vfolder" to not ask again.
