I see the following behavior:

  octave:3> function f (x)
  > inputname (1)
  > end
  octave:4> f (1+2)
  ans = 
  octave:5> x = 1; f (x)
  ans = x

so if an expression is passed to F, inputname (1) returns an empty
string.  Looking at the definition of inputname, I don't see how it
ever returns "ans".
