For classes and interfaces that appear in the index, it should say
"class/interface in package <a>com.package</a> rather than
duplicating the class/interface name.

For example, the index currently says:

<a>AccessControlContext</a> - class java.security.<a>AccessControlContext</a>

Notice there are two links to the same class on the same line, which is
unnecessary.

This should instead be:

<a>AccessControlContext</a> - in package <a>java.security</a>
