1.0.10

• Improve parsing of .0 and .var-style format arguments (#54)

  For example the one here as the argument to the match expression would now be recognized correctly:

  #[derive(Error, Debug)]
  pub enum MyError {
      #[error("{}: {0}", match .1 {
          Some(n) => format!("a variant error occurred with n={}", n),
          None => format!("there was an empty variant error"),
      })]
      Variant(String, Option<usize>),
  }
