Issue #128 Fix unsupported recursive descent targets to match interpreter

Addresses review comment: For unsupported recursive descent targets like
$..[0:2], $..[?(@.x)], or $..['a','b'], the compiled code was incorrectly
adding the current node to results. The interpreter logs and returns no
matches for these cases.

Changed to generate a no-op comment instead of adding to results, which
matches the interpreter's semantics.
