+'message-id' and 'from' now have sensitive characters escaped using\r
+xml.sax.saxutils.escape [1]. The 'subject' data was already being\r
+converted to a link into Gmane; I've escape()d that too, so it doesn't\r
+need to be handled ain the same block as 'message-id' and 'from'.\r
+\r
+This prevents broken HTML by if subjects etc. contain characters that\r
+would otherwise be interpreted as HTML markup.\r
