bad formatting for inline comment for return value

I want this:

```
func (r *limitedCommandResult) AddRow(
ctx context.Context, row tree.Datums,
) (_ /* cont */ bool, _ error) {
```

the tool gives me this:
```
func (r *limitedCommandResult) AddRow(
ctx context.Context, row tree.Datums,
) (
_ bool, /* cont */
_ error,
) {
```
