Get rid of redundant "expected" in error output.
Get rid of redundant "expected" in error output.

I was not able to proof that this "expected" is redundant in all cases,
but it looks like it.

In fact I was not even able to figure out why this was redudant at all,
but it definitely is (at least in most cases).
