Don't generate V: { f: u8, // comment }

[radix]

Fixes #2446

My only concern is that since this uses contains_comment, it also reformats the following code unnecessarily:

enum E {
    V { f: u8, /* hi */ }
}

to

enum E {
    V {
        f: u8, /* hi */
    }
}

I couldn't find any functions like "contains_trailing_comment" which would probably be more appropriate

appveyor failure was a spurious network error. I dunno if there's a way to kick it...

@radix Thank you for you PR!

You could use last_line_contains_single_line_comment over contains_comment.

thanks for the hint @topecongiro ! I've pushed a new revision and updated the test.
