* 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.
