Sun bug numbers without any accompanying text are completely useless.

Fixed with
   git grep -lP '//\s*#\d+#\s*$'
       | xargs perl -i -ne'/\/\/\s*#\d+#\s*$/d or print'
And then hand-checking the result to restore places where it deleted code.
And then some more grepping and hand-editing to kill the others.
