Patch attached. Also added a test case that exercises this code path
by creating a text operator with _int_matchsel as the restriction
estimator.

Good catch, pushed. I didn't bother with the test case though ---
none of the other early exits in that function have test cases,
and I don't see why this one is any more fragile than the others.
