+This happens in buglist.cgi after the standard columns have been defined and
+right before the display column determination.  It gives you the opportunity
+to add additional display columns.

+=item C<columns> - A hashref, where the keys are unique string identifiers
+for the column being defined and the values are hashrefs with the

+=item C<name> - The name of the column in the database.
