Comment:

 I've made a lot of improvements to the Query class API docs in
 [00f69cf3928b44a756ddafcde248610f72babf62] (backported for 1.4.12 in
 [976ea09888503b9c2dc188c9b8111f928b3c19d4]).

 I think that addresses all the issues raised here, so I'm going to close
 this.  It wouldn't be feasible to change how `Query()` or a query
 constructed from an empty iterator pair works at this point as it would
 force an incompatible change on existing code using the API.

 We could perhaps make `Query(OP_INVALID)` behave like you expected
 `Query()` to - if you or somebody else thinks that would be beneficial, we
 could try it and see how it looks in various situations, and whether it's
 actually helpful or just confusing.
