Release go-eldoc 0.21

I released go-eldoc 0.21.
I fixed issue that go-eldoc cannot highlight types of return value
of function which has map type argument.

Example code is here.

package main

import (

func main () {
	profile, err := pit.Get("", pit.Requires{

go-eldoc <= 0.20

The error is occurred.

go-eldoc >= 0.21

Showing types of return value correctly.


I fixed go-eldoc bug and released version 0.21.

Please report me via github issues if you have any problems or suggestions.
