* src/global.c (add_to_sclist), src/help.c (help_init), src/nano.h,
src/rcfile.c (parse_binding): When defining the toggles, give each
of them a sequence number, so that, when they are rebound, they can
still be listed in the original order in the help text.
* src/text.c (do_undo): Make it clearer what WAS_FINAL_BACKSPACE does.
* src/text.c (add_undo, do_deletion): Move the check for a Delete at
the end-of-file to a less frequently travelled path.
