rustfmt removes empty lines between block and doc comments

[nokaa]

With normalize_comments set to false, running rustfmt can lead to empty lines between a block comment and a doc comment being removed.

Here is some example code:

/// Doc comment for func1
/*fn func1() {
    let a = 5;
}*/

/// Doc comment for func2
fn func2() {
    let b = 5;
}

When rustfmt is run, the fifth line will be deleted. This line is only deleted if line 6 is a doc comment; normal and block comments work properly.
It seems that an arbitrary number of empty lines can be between the block comment and the doc comment, they will all be deleted.

If I can help fix this let me know. I don't really want to just open issues that relate to features that I'm the only one using. It would probably be better if I could do the work and submit a pull request for bugs I come across.

Are you using master? We merged a few commits recently that might address this issue.

Yes, I saw that #1185 had been merged when I went to file an issue; so I made sure to use the latest commit for testing.

Closing as this if fixed on the current master.
