Preserve extent information in the command builder code. src/ChangeLog addition: 2014-07-14 Aidan Kehoe <kehoea@parhasard.net> * event-stream.c: * event-stream.c (mark_command_builder): * event-stream.c (finalize_command_builder): Removed. * event-stream.c (allocate_command_builder): * event-stream.c (free_command_builder): Removed. Use free_normal_lisp_object() instead. * event-stream.c (echo_key_event): * event-stream.c (regenerate_echo_keys_from_this_command_keys): Detach all extents here. * event-stream.c (maybe_echo_keys): * event-stream.c (reset_key_echo): * event-stream.c (execute_help_form): * event-stream.c (Fnext_event): * event-stream.c (command_builder_find_leaf_no_jit_binding): * event-stream.c (command_builder_find_leaf): * event-stream.c (lookup_command_event): * events.h (struct command_builder): Move the command builder's echo_buf to being a Lisp string rather than a malloced Ibyte array. This allows passing through extent information, which was previously dropped. It also simplifies the allocation and release code for the command builder. Rename echo_buf_index to echo_buf_fill_pointer, better reflecting its function. Don't rely on zero-termination (something not particularly compatible with Lisp-level code) when showing a substring of echo_buf that differs from that designated by echo_buf_fill_pointer, keep a separate counter instead and use that. * minibuf.c: * minibuf.c (echo_area_append): Use the new START and END keyword arguments to #'append-message, rather than consing a new string for basically every #'next-event prompt displayed. test/ChangeLog addition: 2014-07-14 Aidan Kehoe <kehoea@parhasard.net> * automated/extent-tests.el: Check that extent information is passed through to the echo area correctly with #'next-event's PROMPT argument. lisp/ChangeLog addition: 2014-07-14 Aidan Kehoe <kehoea@parhasard.net> * simple.el (raw-append-message): Use #'write-sequence in this, take its START and END keyword arguments, so our callers don't have to cons as much. * simple.el (append-message): Pass through START and END here.
