--- Comment #2 from larue at cadence dot com ---
Oops, accidentally saved before pasting in the patch (shown below):

char *
n_spaces (int n)
{
  char *t;
  static char *spaces = 0;
  static int max_spaces = -1;
  /* Prevent heap corruption if n is negative (which occurs if
default_print_one_register_info is called with a register whose name
is > 15 characters long */
  if (n < 0)
     n = 0;
  if (n > max_spaces)
    {
      if (spaces)
        xfree (spaces);
      spaces = (char *) xmalloc (n + 1);
      for (t = spaces + n; t != spaces;)
        *--t = ' ';
      spaces[n] = '\0';
      max_spaces = n;
    }

  return spaces + max_spaces - n;
}
