	* cpplib.c: Make all directive handlers read their own
          arguments.
	  (struct directive): Remove last two arguments from FUNC
          member prototype. Remove `command_reads_line' member
          entirely.
	  (directive_table): Remove initializations of
          command_reads_line flag.  Pretty-print.
	  (eval_if_expression, do_define, do_line, do_include,
          do_undef, do_error, do_pragma, do_ident, do_if, do_xifdef,
          do_else, do_elif, do_sccs, do_assert, do_unassert,
          do_warning): Take only two args.
	  (cpp_define): Call do_define with two args and the text to
	  define stuffed into a buffer.
	  (make_assertion): Call do_assert with two args.
	  (handle_directive): Call do_line with two args. Call
	  kt->func with two args.  Remove command_reads_line
	  processing.
	  (do_define, do_undef, do_error, do_warning, do_pragma,
	  do_sccs): Read the rest of the line here.
	  (do_ident): Gobble rest of line, as cccp does.
	  (cpp_undef): New function.
	  (cpp_start_read): Call cpp_undef instead of do_undef.
