        * files.c (do_writeout): Add check for file modification when saving
          the file so the user can at least know they may be blowing away changes.

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

        * files.c: (write_file): Add needed flags to open() calls when writing out files.  Fixes Savannah bug

- 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 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.

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.
