Comment before } else { is incorrectly indented

[ghost]

Code:

fn main() {
    if true {
        // Create a guard.
        let guard = create_guard();
        // The guard goes out of scope.
    } else {
    }
}

After rustfmt:

fn main() {
    if true {
        // Create a guard.
        let guard = create_guard();
    // The guard goes out of scope.
    } else {
    }
}

Perhaps all lines within blocks (even comments) should always be indented more than the lines with block boundaries?

This is intended behavior (cc #1575, #1619).
You can set format_if_else_cond_comment to false to indent the comment.

@topecongiro Would it make sense for rustfmt to simply leave indentation of such comments intact?

To illustrate, I'm suggesting that rustfmt formats the following:

if true {
    foo();
        // a
} else if true {
    bar();
    // b
} else  if true {
    baz();
// c
} else {
    quux();
}

Into this:

if true {
    foo();
// a
} else if true {
    bar();
    // b
} else  if true {
    baz();
// c
} else {
    quux();
}

That strategy would do the right thing in almost all cases.

You can set format_if_else_cond_comment to false to indent the comment.

It looks like this option has been removed from rustfmt and now there is no way to override this behaviour.
