* editfns.c (find_field): Formatting changes.
(toplevel): Some old-style function forward declarations
changed to prototypes, some new protypes added, some functions
made static.
* lisp.h (set_time_zone_rule): Add prototype.
(use_dialog_box): External declaration.
* keyboard.c (gen_help_event): Add parameter SIZE.
(kbd_buffer_events_waiting): Slightly rewritten.
(clear_event): New function.
