Improve help message in module CLI operation

Improve help message in module CLI operation:
module --help

--resources and --absolute-resources description contains example of path separator, example is java.io.File.pathSeparatorChar. This example could be confusing for EAP administrators without experience with java. It would be better to mention example for Windows and Linux OS:

So I suggest to replace this:
separated by a filesystem-specific path separator, i.e. java.io.File.pathSeparatorChar.
by something like this:
separated by a filesystem-specific path separator, i.e. '/' for Linux and '\' for Windows.
