I’d like to check my understanding of the Path.wildcard/2 documentation

It states:

* - matches any number of characters up to the end of the filename, the next dot, or the next slash.

However, the following wildcard: Path.wildcard("**/*.ex") matches the file lib/test.pb.ex. But if the documentation is to be believed, it shouldn’t match as the * should only match up to the dot between test and pb, and the remaining pattern .ex does not match pb.ex.

What’s going on here? Is this a bug, is the documentation wrong, or is my understanding incorrect?

Thanks
