        * 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.
