% Whether minted itself knows 'cacheignoresfilecontents' is minted's own
% compatibility, not osglistings' -- osglistings only promises to forward
% the option and to degrade gracefully where minted can't honor it (see
% osglistings.dtx). So this only exercises that path for crashes; it makes
% no claim about minted's resulting internal state, which differs by
% version.
