drop the "enable".

[floitsch, 2016/02/23 10:40:48]

Think about it: make sure this contains "syntax" in the name:
--generic-method-syntax

Otherwise you conflict with the existing flag from the analyzer, and it will
become harder to add the semantic flag (which I would then call
'--generic-methods'.
