+       Make PSPP able to read all the portable files I could find on the
+       web.  Thanks to John Darrington for review.  Bug #17620.
+       * por-file-reader.c (struct pfm_reader): New member `line_length'.
+       (error): Print file offset in hexadecimal.
+       (warning): New function.
+       (advance): Treat lines less than 80 bytes long as padded to 80
+       bytes with spaces.
+       (pfm_open_reader): Call read_documents if we find an "E" record.
+       (convert_format): Convert invalid formats to the default format
+       instead of aborting reading the file.
+       (read_variables): Rename duplicate variable names instead of
+       aborting reading the file.
+       (read_value_label): Allow string variables of different widths to
+       be assigned value labels in the same record.  Replace duplicate
+       value labels instead of aborting.
+       (read_documents): New function.
+
+       * por-file-writer.c (pfm_open_writer): Call write_documents if the
+       dictionary has documents.
+       (write_documents): New function.

+       Fix bugs related to bug #17213.
+
+       * settings.c: Use HAVE_LIBNCURSES instead of HAVE_LIBTERMCAP,
+       since the former is what config.h has.  Include the needed ncurses
+       headers.
+       (static var echo) Rename to `do_echo' because the original name is
+       the same as an ncurses identifier.
+       (get_termcap_viewport) Use error instead of msg.
+
+       * file-name.c (fn_interp_vars): Fix interpolation of $VARS.
+       (fn_close): Don't close stdin, stdout, stderr.

+
+       * procedure.c procedure.h: Added callbacks which get invoked whenever 
+       a dataset's transformation chain changes.

+
+       Fix bug #6113.
+       * sys-file-writer.c (write_variable_display_parameters): Use new
+       var_default_display_width function to choose display width of
+       segments after the first one in a given variable.
+       * variable.c (var_create): Use var_default_display_width to pick
+       new variable's display width.
+       (var_default_display_width): New function.
