+       * src/text.c (do_redo, update_undo):  Redo an Enter from the stored
+       undo data, instead of running do_enter() again, because the latter
+       will behave differently depending on the setting of autoindent.
+       This addresses Debian bug #793053 reported by Clancy.

        * src/winio.c (edit_draw): Skip a zero-length match only when there
        /is/ a match.  Found with valgrind.  This fixes Savannah bug #41908.
