This intends to make the implementation consistent with the documentation.

In short, Databroker does not know if A.B refer to a signal A.B or a branch A.B.
We solve that by both looking for A.B.** and A.B.
That is OK as if there is a signal A.B there cannot be a branch A.B,
even if it may require somewhat more comparisons, but you cannot do it in one comparision using glob.

Also our current glob cargo package does not seem to be maintained,
we may consider migrating to something else.

Otherwise quite useless if you request data with wildcard
