type == CUT in add_undo (?!)

        * configure.ac, rcfile.c:  Add support for an alternate rcfilename at configure time.  Maybe this
          should become a command line option some day, but I don't see the need currently.  Start of   
          fix for Savannah bug #24128: Add nanorc support to win32 platform.
