[Texmacs-dev] Inconsistant contains for list and array

[Darcy Shen]

We may rewrite the contains for array.

For list:

template<class T> bool

contains (list<T> l, T what) {

  return (!is_nil(l) && (l->item == what || contains(l->next, what)));

}

For array:

template<class t> bool

contains (t a, array<t> b) {

  int i, l= N(b);

  for (i=0; i<l; i++)

    if (a == b[i])

      return true;

  return false;

}
