 * XXX This is a bit clunky. We typically pass in:
 * - simple_dialog_primary_start
 * - The primary message
 * - simple_dialog_primary_end
 * - Optionally, the secondary message.
 *
 * In the GTK+ UI primary_start and primary_end make up a <span> that adds
 * text formatting. The whole string is then shoved into a GtkLabel.
 *
 * In the Qt UI we use primary_start and _end to split the primary and
 * secondary messages. They are then added to a QMessageBox via setText and
 * setInformativeText respectively. No formatting is applied.
 *
 * Callers are responsible for wrapping the primary message and formatting
 * the message text.
 *
 * Explicitly passing in separate primary and secondary messages would let us
 * get rid of primary_start and primary_end and reduce the amount of
 * gymnastics we have to to in the Qt UI.
