/* comments */ are sometimes formatted away in function declarations

[wooster0]

fn x<T: Clone>/* pls don't format me away */(x: T) {}

fn x/* pls don't format me away */<T: Clone>(x: T) {}

fn /* pls don't format me away */x<T: Clone>(x: T) {}

All of these examples are formatted to

fn x<T: Clone>(x: T) {}

but I expect the comment to stay.
