One problem with the solutions already posted here is that they redirect all output to the console, so if I run ./myprogram >file, the redirection to file gets lost. I've written a new module, github.com/apenwarr/fixconsole, that avoids this problem. You can use it like this:

import (
        "fmt"
        "github.com/apenwarr/fixconsole"
        "os"
)

func main() {
        err := fixconsole.FixConsoleIfNeeded()
        if err != nil {
                fmt.Fatalf("FixConsoleOutput: %v\n", err)
        }
        os.Stdout.WriteString(fmt.Sprintf("Hello stdout\n"))
        os.Stderr.WriteString(fmt.Sprintf("Hello stderr\n"))
}
