When a formatting string contains an invalid descriptor, point at it
instead of the argument:

error: unknown format trait `foo`
  --> $DIR/ifmt-bad-arg.rs:86:17
   |
LL |     println!("{:foo}", 1);
   |                 ^^^
   |
   = note: the only appropriate formatting traits are:
           - ``, which uses the `Display` trait
           - `?`, which uses the `Debug` trait
           - `e`, which uses the `LowerExp` trait
           - `E`, which uses the `UpperExp` trait
           - `o`, which uses the `Octal` trait
           - `p`, which uses the `Pointer` trait
           - `b`, which uses the `Binary` trait
           - `x`, which uses the `LowerHex` trait
           - `X`, which uses the `UpperHex` trait
