I think you're right, but I need to check all usages of this function to prevent this modification from accidentally breaking something. |

Ref: #1051
I think the semantic of
ContainsByEndshould be: "Please check whether this key is in the range, if the input is empty, treat it as infinity.". But I have noticed there are already some test cases that believes "" shouldn't be in ("", ""]. I'm not sure whether it is by design.Anyway this will bring unexpected behavior sometimes (say, make infinity loops), I think perhaps we can make it better.
