+
+ Don't offer both the full and abbreviated names for a single
+ command in command name completion.
+
+ * command.c: (enum flags) Add F_ABBREV flag.
+ (cmd_complete) Ignore command with F_ABBREV flag set.
+
+ * command.def: Add F_ABBREV to N, Q, SORT commands.

+
+ Fix regression in command name completion reported by John
+ Darrington. Now completion is again state-dependent and occurs
+ only on the first line of a command.
+
+ * command.c (do_parse_command): Move reading the first token of
+ the command here, from execute_command and cmd_input_program.
+ Call set_completion_state and getl_set_prompt_style here.
+ (do_parse_command) Use in_correct_state instead of
+ verify_valid_command.
+ (verify_valid_command) Break into two new functions,
+ in_correct_state and report_state_mismatch.
+ (set_completion_state) New function.
+ (cmd_complete) New function.
+ [HAVE_READLINE] (pspp_attempted_completion_function) Removed.
+ [HAVE_READLINE] (command_generator) Removed.
+
+ * line-buffer.c: (struct getl_source) Change `interactive' member
+ signature to take enum getl_prompt_style instead of const char *.
+ (create_interactive_source) Ditto, for parameter type.
+ (getl_append_interactive) Ditto.
+ (read_line_from_source) Pass get_prompt_style() to interactive
+ function instead of get_prompt().
+ (get_prompt) Removed.
+ (get_prompt_style) New function.

+
+ Continue reforming procedure execution. In this phase, remove
+ PROCESS IF, which was deprecated anyway and can be easily
+ simulated with TEMPORARY followed by SELECT IF.
+
+ * command.def: Removed PROCESS IF.
+
+Mon May 1 18:17:52 2006 Ben Pfaff <blp@gnu.org>
+
+ Further clean up the CMD_* command result codes.
+
+ * command.c (cmd_result_is_valid): New function.
+ (cmd_result_is_success) Assert that argument is valid. Simplified
+ check to one for a positive result.
+ (cmd_result_is_failure) Assert that argument is valid. Simplified
+ check to one for a negative result.
+ (do_parse_command) Check that command's returned result is valid.
+
+ * command.h: (enum cmd_result) Renamed CMD_QUIT to CMD_FINISH and
+ updated all users. Removed CMD_END_SUBLOOP in favor of new
+ CMD_PRIVATE_FIRST...CMD_PRIVATE_LAST range. Changed failure codes
+ to have negative values.
+
+Mon May 1 15:56:56 2006 Ben Pfaff <blp@gnu.org>
+
+ Remove vestiges of FILE TYPE support.
+
+ * command.def: Mark FILE TYPE, RECORD TYPE unimplemented.

CLEAR TRANSFORMATIONS is unsafe as implemented. It's a fair
