Clarify precidence rules for odata.include-annotations preference

In the description for precedence of terms in the odata.include-annotations preference we say "The most specific identifier always takes precedence."

This was intended to imply that, if you have two rules (Foo.* and Foo.Bar.*)that can match a particular annotation (Foo.Bar.blah), the most specific match wins (Foo.Bar).

I recently got a question whether the wording implies that, if you have "Foo." and "Foo.Bar.", then it's the same as "Foo.Bar.*" – i.e., that adding the more specific identifier makes it as if the former was not specified.

I don't think this will be a common misinterpretation, but perhaps we should clarify just in case.
