Stéphane Campinas 84c2356590 handle unicode chars in closures (#3632)
The `NotUnicode` branch was unecessarily put on a new line, although it
was within max width:

```diff
 fn baz() {
     let our_error_b = result_b_from_func.or_else(|e| match e {
         NotPresent => Err(e).chain_err(|| "env var wasn't provided"),
-        NotUnicode(_) => Err(e).chain_err(|| "env var was very very very bork文字化ã"),
+        NotUnicode(_) => {
+            Err(e).chain_err(|| "env var was very very very bork文字化ã")
+        }
     });
 }
```
