formatting of maps is invalid go code

[awalterschulze]

package main

import (
	"fmt"

	"github.com/kr/pretty"
)

type A struct {
	B *B
}

type B struct {
	M map[string]string
}

func main() {
	a := &A{B: &B{M: map[string]string{}}}
	fmt.Printf("%# v\n", pretty.Formatter(a))
        //prints out
	/*
		&main.A{
		    B:  &main.B{
		        M:  {},
		    },
		}
	*/
        //This contains a syntax error
	c := &A{
		B: &B{
			M: {},
		},
	}
}

This line M: {} gives the error: missing type in composite literal

I would really love to be able to print valid go source.

This problem is also present for slices of structs and non empty maps.

This tool is really quite useful. Good work.

I was also wondering, like above, if you plan to fix this soon?
