+       Improve the way we handle the various parsing "states".  Until now
+       we've hard-coded the state transitions in the command definition
+       file, but that's error-prone and, worse, it's redundant--we can
+       figure out what state we're in anyhow.  We can cleanly handle
+       INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
+       
+       * procedure.c (case_source_is_complex): Removed.
+       (discard_variables) No need to set pgm_state anymore.

+       Finish reforming error message support.  In this phase, move
+       message.c into libpspp.
+       
+       * message.c: Move to libpspp.

+
+       Continue reforming error message support.  In this phase, drop
+       actual message printing from core code, substituting a callback,
+       and add the callback to each UI.  Also, move verbose_msg() into
+       its own module.
+
+       * message.c: (var err_error_count) Renamed error_count and moved
+       to ui/terminal/msg-ui.c.
+       (var err_warning_count) Renamed warning_count and moved to
+       ui/terminal/msg-ui.c.
+       (err_check_count) Renamed check_msg_count() and moved to
+       ui/terminal/msg-ui.c.
+       (dump_message) Rewrote to take stream instead of function pointer
+       and moved to ui/terminal/msg-ui.c.
+       (msg_emit) Moved its guts to ui/terminal/msg-ui.c as handle_msg()
+       and rewrote to just pass message to callback.
+       
+       (var err_verbosity) Renamed "verbosity" and moved to
+       libpspp/verbose-msg.c.
+       (verbose_msg) Moved to libpspp/verbose-msg.c.
+       
+       (var err_already_flagged) Removed.
+       (puts_stdout) Removed.
+       
+       (var msg_handler) New static variable.
+       (msg_init) New function.
+       (msg_get_command_name) New function.

+
+       Continue reforming error message support.  In this phase, rename
+       all the message functions and types to start with "msg", except
+       for the ones that will be moving to other modules anyway.
+
+       All references to the identifiers below were updated likewise.
+       
+       * message.c: (err_done) Renamed msg_done().
+       (err_push_file_locator) Renamed msg_push_msg_locator().
+       (err_pop_file_locator) Renamed msg_pop_msg_locator().
+       (err_location) Renamed msg_location().
+       (err_set_command_name) Renamed msg_set_command_name().

        * message.c: Use exit.h from gnulib instead of checking for and
