not all inputs are printed with -ins flag

[5nizza]

The call

syfco -ins ./ltl2dba10.tlsf

gives p, q, but the benchmark has inputs p, q, r (note that r is never used). Here is the file:

INFO {
  TITLE:       "LTL -> DBA  -  Example 10"
  DESCRIPTION: "One of the Acacia+ example files"
  SEMANTICS:   Moore
  TARGET:      Mealy
}

MAIN {
  INPUTS {
    p;
    q;
    r;
  }
  OUTPUTS {
    acc;
  }
  GUARANTEES {
    G (p -> F q)
      <-> G F acc;
  }
}
