Verify Matcher vs. OpenJDK 8u121-b13, step 6.

Reinstate documentation for referencing named groups.

These two lines of documentation now exactly match upstream
OpenJDK 8u121-b13. The documentation had previously been omitted
because Android didn't use to support named groups, but such
support was added for Android 8.0 Oreo in libcore CL [1].
