Hello Christian, I think this change in the description of the syntax for arg files is accurate and removes any confusion. 

While at it, I think we should also do a small update to the following line in the section "Using the JDK_JAVA_OPTIONS Launcher Environment Variable":

> However, as in `@`-files, use of a wildcard is not supported.

Based on what I see in the launcher code which handles the `JDK_JAVA_OPTIONS` environment variable, I think we should just change it to:

> The wildcard literal `*` isn't expanded and is passed as-is to the `java` launcher.
