	* macro.c: Delete unnecessary function declarations.
	(buffer_and_nest): Support multiple labels per line for
	LABELS_WITHOUT_COLONS targets if the labels do have colons.
	(free_macro): Move so that we don't need forward declaration.
	* read.c (read_a_source_file): Take a copy of macro expansion line
	before we trim labels.
	* listing.c (listing_newline): Adjust stdin line save for
	input_line_pointer still at start of line.
gas/testsuite/
	* gas/macros/dot.s: Don't start macro invocations is first column.
	* gas/macros/dot.l: Update.
	* gas/macros/macros.exp: Run dot test on more targets.
