Unexpected formatting of macro with block when hard_tabs = true.

[nitsky]

Describe the bug

I am observing unexpected formatting of macro bodies when the macro emits a block wrapped in curly braces and hard_tabs = true.

To Reproduce

Run the following macro definition through rustfmt with hard_tabs = true:

Input:

macro_rules! example {
	() => {{ let x = 5; Ok(x) }};
}

Output:

macro_rules! example {
	() => {{
		let x = 5;
		Ok(x)
		}};
}

The output has an extra level indentation at the closing curly braces. This does not happen when hard_tabs = false or when the macro does not emit an enclosing block.

Expected behavior

#[macro_export]
macro_rules! example {
	() => {{
		let x = 5;
		Ok(x)
	}};
}

This has been fixed in source but not backported to a 1.x release. Let me see if I can squeeze this in the upcoming v.1.4.28 release

Closing as a duplicate of #4152, fix has been backported and will be in the next release
