         * With a small window, if 3 or more buttons are shown horizontally,
         * there is a ridiculous amount of space for the text. And it can get
         * worse since the button labels are translatable, in other languages it
         * can take even more place. If the buttons are packed vertically, there
         * is no problem.

+        * The GtkInfoBar implementation comes originally from gedit, and the
+        * action area was vertical. Then IIRC a GNOME designer decided that the
+        * action area must be horizontal, making the gedit info bars look
+        * weird... So, come back to the original design.
