+%   We avoid some hyperref warnings by making |\\| (almost) trivial in
+%   bookmarks: more precisely it might be used with a star and an
+%   optional argument, which we thus remove using an \pkg{xparse}
+%   expandable command.  Since there cannot be trailing optional
+%   arguments, pick up an extra mandatory one and put it back.
