Previous discussion on whether or not to remove support for javac
-source/-target-/--release from JDK 11 settled instead on removing that
functionality from JDK 12 .
That removal has now been pushed to jdk/jdk.  A small related
enchantment shows the set of supported -source and -target alternatives
in javac's -help output.
