Set the minimum_width.
2000-01-28 Christopher James Lahey <clahey@helixcode.com> * widgets/test-reflow.c: Set the minimum_width. * widgets/e-reflow.h, widgets/e-reflow.c: Added one more column line so that the right edge of the reflow will have a line. Also added a minimum_width so that even if the reflow is thinner than the window, when you resize it larger all the lines are drawn. svn path=/trunk/; revision=1648
