* stack.c (do_gdb_disassembly): Use RETURN_MASK_ERROR, simplify the
	exception_print code path.
	(backtrace_command): Remove variable e.  Protect arg by make_cleanup in
	advance.  Simplify memset.  Remove TRY_CATCH.  Remove explicit xfree.
	(backtrace_full_command):  Remove variable e.  Remove TRY_CATCH.
