Well no it is not normal to be empty. It is normal for the top-context range 
not to have the exact size of the document though.

The only contexts that have empty ranges are usally those that were expanded 
by a preprocessor macro, since they cannot have a valid range in the document.

If you don't want "findContextIncluding(Range)" to return you such empty 
ranges, then you should call it non-empty ranges, as only empty ranges can be 
contained by an empty range.
