+       * format.c: (fmt_date_template) Distinguish characters for which a
+       space is output and any date delimiter is allowed on input, from
+       those for which a space is output and only a space is allowed on
+       input.  The former is represented by X, the latter by a space.
+       Also, drop distinction between h and H, changing the former to the
+       latter.
+
+       * data-in.c: Completely rewrite internals to conform to SPSS input
+       formats as closely as possible.
+       (data_in) Changed external interface by replacing the structure
+       that was used as a single argument by a set of arguments.  Updated
+       all callers.
+       (data_in_finite_line) Removed.  Converted all callers to use plain
+       data_in.
+       (data_in_get_integer_format) New function.
+       (data_in_set_integer_format) New function.
+       (data_in_get_float_format) New function.
+       (data_in_set_float_format) New function.
+
+       * data-in.h: (enums DI_IGNORE_ERROR, DI_IMPLIED_DECIMALS) Removed.
+       (struct data_in) Removed.
+
+       * data-out.c: (output_date) Drop each component from the input as
+       it is output, to allow us to drop the distinction between h (a
+       count of hours) and H (the hour of day) template characters.
+       Also, handle new X template character.
+       (output_scientific) Follow more rational rule on when to drop
+       fraction introduced between SPSS 13 and 15.  Updated test case to
+       match new behavior.
