gorun fmt

[ericcurtin]

A C/C++ programmer primarily, looking to learn something new, golang! One of the things I first thought is what great potential it had as a statically typed scripting language! And I really like how you cache compiled binaries here, pretty cool.

Anyway long story short... I'd like to introduce a "gorun fmt" option to format my gorun scripts... Because if you pass through normal go fmt it doesn't like the shebang of course:

go fmt hello_world.go 
can't load package: package main: 
hello_world.go:1:1: illegal character U+0023 '#

If I open a PR would you except a "gorun fmt" option? Don't want to waste effort if it wouldn't be accepted!

@ericcurtin one option is to run it as comments, then you can run go fmt on it fine:

//usr/bin/env gorun "$0" "$@"; exit "$?"

package main

func main() {
    println("Hello worldz!")
}

Somehow this also works and gofmt won't change the code. It adds a space after the comment

// / 2>/dev/null ; gorun "$0" "$@" ; exit $?

Just add an empty line before this gorun line and a package main line. This way this comment won't be considered a "package comment" and gofmt won't change it.
