% A lot of the ifrightifleft environment's logic has to be duplicated in \margdown -- if changing it here,
% change it there as well. This has to be implemented as an environment, so that the label occurs at the
% end; otherwise it messes up if it's the first thing on the page, because the label's page number refers
% to the previous page.
