Bugs in set_buffer?

This has been there a long time, but is it right? 

  static void
  set_buffer(Param pm, char *x)
      if(x) {
	  unmetafy(x, &ll);
	  strcpy((char *)line, x);
	  if(cs > ll)
	      cs = ll;
      } else
	  cs = ll = 0;
      menucmp = 0;

If the unmetafy() had any effect, then x may (i) contain a NULL, so the
strcpy() should be a memcpy() (this is exactly why we need ll at all),
(ii) be a different length from the one supplied, so zsfree() isn't good
enough to free it properly.

Have I missed something?
