What did you do?

fn main() {
    mut x := 0
    if x == 0 {
        println(true)
    }

    println(x)
}

v fmt file.v



md5-bf3ad3fcbed996e8ee8b76d23000b67c



fn main() {
        mut x := 0
        if x == 0 {
                println(true)
        }
        println(x)
}

Explanation

As example, in my company we have a rule keep an empty line after each for, if, while block etc.
Some dudes do this for better code readability. So we should provide that option for the developers. Beeing too strict may result in rejection.

Allow one empty line. Compress multiple empty lines into one.

Looks like #3917
