vector.c, rewrite vec_basename(), FIXME !

Browse Source 
This rewritten code is functionally equivalent to the previous code,
yet the result is queer,
because the char *v_name slot of struct dvec is read
beyond its terminating '\0'

Is there indeed some code in ngspice which creates
v_name strings with an embedded '\0' ?
