        * New saved cursor position history option.  Command line option -P or --poslog, rc file
          entry "poslog".  Search history changes to ~/.nano/search_history, cursor position log
          is ~/.nano/filepos_history.  Added checks to move the legacy .nano_history file to the new
          location.  Several new functions to files.c: load_poshistory(), save_poshistory(),
          check_poshistory(), update_poshistory(), and reworking of histfilename().  New FAQ entry
          4.15 discussing the change and offering an interoperability workaround.

          This does add 20KB to nano's executable size but it gets rid of a lot of indirection
          that makes people stomach turn.  There are several new stub functions and need of more
          tidying as a result of this.

	  with new function prompt_failed_backupwrite(), allows more secure handling of problems

        * New option allow_insecure_backup, allows the previous security
          fixes for backup files to be overridden if you're really positive
          you want to.  Fixes Savannah bug 29732 by Brian Szymanski <skibrianski>.

        * files.c (write_file): Don't even try to chown() the backup
          file unless we're root, since it's probably going to fail if
          we're editing a file we don't own.  Fixes Savannah bug

        * files.c (wirte_file): Don't set current_stat when tmp == TRUE, check
          whether current_stat is set when trying to use it, and don't do the
          modification check if the filename changed, since we have no way
