as redoing all the menus to have proper, or at least non-hallucinogenic, keyboard accelerators. This requires my recent update to libdialog to work properly and will probably also exhibit some other "interesting" behavior while the last few missing screen clears are found (which is why I'm not going to MFC immediately). At least now, however, sysinstall does not gratuitously redraw random screens at the drop of a hat and drive serial console installers out of their minds.
