* cpptrad.c (scan_out_logical_line): Check recursing only when

	we know we have a macro invocation in the function-like case.
	Only call _cpp_handle_directive if we know we have a good
	directive, or we want to reject a bad directive.
testsuite:
	* gcc.dg/cpp/trad/argcout.c, gcc.dg/cpp/trad/assembler.S,
	gcc.dg/cpp/trad/argcout.c, gcc.dg/cpp/trad/funlike-4.c,
	gcc.dg/cpp/trad/null-drctv.c, gcc.dg/cpp/trad/recurse-1.c,
	gcc.dg/cpp/trad/recurse-2.c, gcc.dg/cpp/trad/recurse-3.c:
	New tests.
	* gcc.dg/cpp/trad/directive.c: Update.
