Comments after the first one in empty struct are not formatted nicely

[wooster0]

struct Struct {
    // Hello, this is my
    // struct where I haven't added
    // any fields yet.
    // TODO: add fields
}

If you format this code, it becomes:

struct Struct {
    // Hello, this is my
// struct where I haven't added
// any fields yet.
// TODO: add fields
}

I expected it to stay the way it is because it already looks perfectly fine and leaving only the first comment indented looks odd.

Thanks for sharing! Seems to occur with other struct types
e.g.

struct Foo(
    // Bar
    // Baz
    // Qux
);

so probably a general indentation issue with empty struct defs

For anyone interested in working on this a good starting place to look in the code would probably be here:
