x/tools/gopls: bad formatting with CRLF line ending

Seems that this issue has come back - we need a proper way to test this.

Before:

```go
package main

/*
Gronk description
*/
func Gronk() {
    d.New()
}
```

After:

```go
package main

/*
Gronk description
*/
*/
func Gronk() {
    d.New()
}
```
