          issues with --disable-help, especially that do-writeout was treating ^G the same as ^M.

        * configure.ac, color.c, rcfile.c, utils.c: 1st attempt at supporting systems which don't support
          GNU-style word boundaries.  New function fixbounds() to translate from GNU-style to
          BSD-style, autoconf option GNU_WORDBOUNDS.

- Change add_undo and current_undo to only take action arg, as openfilestruct arg is always openfile
- Add ability to undo a file/cmd insert, needed to add undoable flag to read_file and open_buffer as a result

Add undoing argument to do_cut_text as we don't want to be messing around with the undo contents when we're in the 
middle of an undo.

Add beginning undo feature, since I want to start fixing bugs from savannah and don't want to manager another checking, and the code basically works for some operations.

- Change do_prompt and get_prompt_line to pass meta_key and func_key
  so the calling program can DTRT when it calsl get_shortcut.  In
  particular this allows the "new file buffer" toggle on the insert file
  menu to work, and presumably other rebinding stuff should now work also.

- Fix tiny mode compilation problems
- Fix F-keys not working (silly typo)
- Change file browser to use new backend
- global.c - new helper function sc_seq_or, makes logic simpler down in the functions than calling first_sc_for directly

and toggles and sc for shortcut keys, old 'shortcut' and 'toggles' structs are
gone.  The current implementation has a bunch of broken stuff (some of which is
documented in BUGS).  Updated nanorc.5 with some mostly complete documentation
on configuring.
