The legacy indent rule currently ignores arrow functions in parameters
to allow callbacks to not align with the other arguments:
this._someFunctionWithFairlyLongishName(arg1, arg2, arg3,
() => {
this._someOtherFunctionWithLongName(arg1);
});
But as ignoring entire nodes means we can end up with arbitrary
indentation, we should drop the exception. While this would make
the above "illegal" under the legacy config, it conforms with the
non-legacy style, so everything should be fine ...
... except that eslint starts to complain about some function args
that should be fine under the legacy config. Maybe it's thrown off
by the function-arg-in-arrow-function-in-function-arg structure, but
rather than figuring it out, let's just move those to the new style.
