    Prettier inserts a trailing comma to single type parameter for arrow functions in tsx, since v 1.18. But, this feature inserts a trailing comma to type parameter for besides arrow functions too (e.g, function , interface). This change fix it.

    <!-- prettier-ignore -->

      // Input
  interface Interface1<T> {
    one: "one";
  }
  function function1<T>() {
    return "one";
  }

  // Output (Prettier 1.18.0)
  interface Interface1<T,> {
    one: "one";
  }
  function function1<T,>() {
    return "one";
  }

  // Output (Prettier 1.18.1)
  interface Interface1<T> {
    one: "one";
  }
  function function1<T>() {
    return "one";
  }

    When using overrides in the config file, Prettier was not matching dotfiles (files that start with .). This was fixed in 1.18.1
