unrecognized cop Syntax found

[tmorris-fiksu]

$rubocop --auto-gen
generates a rubocop-todo.yml file with the following lines:

Syntax:
  Enabled: false

However, this leads to:

Warning: unrecognized cop Syntax found in .../.rubocop.todo.yml

Please let me know if that is enough to go on, or if you need a test case. The project that generated it is pretty big, and I'm not sure which file caused these broken lines.

Turns out, it's actually really easy to create this warning. Note that I think it is fine for --auto-gen not to be able to cause Errors to be ignored. However, the warning line is a problem, so I guess that the Syntax: line should simply not be emitted.
