NoEmptyLinesOpeningClosingBraces should respect comments when determining which blanks lines are at the beginning/end of a function

[bnbarham]

The NoEmptyLinesOpeningClosingBraces swift-format option will remove blank lines from the beginning/end of blocks, eg.

func myFunc() {

    var x = 3
    return x

}

is reformatted into:

func myFunc() {
    var x = 3
    return x
}

But comments are ignored, eg.

func myFunc() {
    // Some comment here

    // Do a thing
    var x = doAThing()

    // Some other comment here
}

ends up as:

func myFunc() {
    // Some comment here
    // Do a thing
    var x = doAThing()
    // Some other comment here
}

I would expect the input to remain unchanged in this particular case.

Yes, that looks like a dupe. Thanks for noticing, @andre-richter 🙏🏽
