Changes to do_lockfile and write_lockfile to check for EACCESS and change
the return value of the functions (0 instead of -1)

        * 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 overlapping strings highlighting each other.  new variables in edit_draw
          (slmatcharray, pbegin, paintok), new logic (with repeated setting od values in the
          array but its BFI after all).  FIXME: Need to create a new 'overlap'
        * 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!

        * text.c (do_enter): Only increment totsize by the auto-indented amount, size the previous line's size was
          already counted.  Fixes bug reported by Robert Spanjaard.

	  before we try to run the magic check on it.  Fixes error messages to stderr
	  when reading in files that don't exist, reported by Mike Frysinger.

        * 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.

	* files.c (write_file) - Fix problems with writing the backup file (albeit interactively)
	  with new function prompt_failed_backupwrite(), allows more secure handling of problems
	  with failing to write the backup file compared to 'allow_insecure_backup'.
	* winio.c (edit_redraw): Removed unused variable

        * Add check for RESTRICTED mode back to speller, suspend and insert file
          routines, since adding key bindings broke the fact that they should be
          disabled in restricted mode.  Fixes Savannah bug 31625 reported by
          Charlie Somerville.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4519 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * 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
          29514: [nano 2.2.2] backup should ignore chown errors.

        * 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
          of knowing about it in that case.  Fixes Savannah bug 29392, reported
          by Mike Frysinger.

          original file's device ID and inode number as reasons to warn the
