Permit XML entities to be escaped in template output. Useful for creating XML documents directly from Hg logging. Can also be used for HTML. For use in content, will escape '&', '<', and for completeness '>' (although it is not strictly necessary). For use in attributes, will also escape ' and ". Will also replace nonprinting (ASCII) control characters with spaces, since these are illegal in XML.
