        * rcfile.c - Allow syntaxes to be extended via "extendsyntax"
          directive.  Color, header, magic and linter should all be

        * src/*: Introduce (basic) vim-style file locks.  Does not allow vim to recover
          our files, and doesn't yet support setting the file as modified; just lets a 
          vim user know we're editing a file.  Commands line "-G" or "--locking", nanorc 
          option "locking".  New functions src/files.c:do_lockfile(), write_lockfile(),
          and delete_lockfile().

          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.

Add in rcfile support for undo since it would be bad to overly punish the masochists who want to try it out and hopefully submit bug reports.
