        * 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().

        * src/*: Fix a silly issue with the argument to nregcomp, as it's confusing to the caller
        * src/nano.h: Change the color types to a compiler macro (COLORWIDTH), may not actually
          even be worth doing, but someday who knows how wide a color curses implementation might
          be, and maybe we'll even start checking for it in autoconf!

          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.

          routines, since adding key bindings broke the fact that they should be

          file unless we're root, since it's probably going to fail if
