----------------------------

[~ggregory] 

I made some changes, but how can I create merge request in [https://gitbox.apache.org/repos/asf/commons-io.git?] I don't have developer access to it.

> FilenameUtils.#normalize states in javadoc that //foo//./bar becomes /foo/bar
> {code:java}
> System.out.println(FilenameUtils.normalize("//foo//./bar"));
> System.out.println(FilenameUtils.normalize("\\\\foo\\\\.\\bar"));
> {code}
> Result:
> {code:java}
> //foo//bar
> //foo//bar
> {code}
> So, javadoc says, that it should be /foo/bar. I think, that //foo is prefix, so it should be //foo/bar. But in real life it becomes the third way (//foo//bar).
>  
> I think we should fix javadoc and the code. The correct result should be //foo/bar
