What version of Go are you using (go version)?

$ gotip version
go version devel go1.21-f00c54146c Mon Apr 10 22:52:22 2023 +0000 linux/amd64

Does this issue reproduce with the latest release?

This tests a change made on tip.

What operating system and processor architecture are you using (go env)?

NA

What did you do?

Given this file:

// Package p is a package.
//
//magic:true
package p

// T is a type
//
//magic:true
type T struct {
	// Field is a field
	//magic:true
	Field int
}

go 1.20 go doc shows:

$ go doc --all .
package p // import "hockin.org/p"

Package p is a package.

TYPES

type T struct {
	// Field is a field
	//magic:true
	Field int
}
    T is a type

Note the directive line is present. gotip doc says:

$ gotip doc --all .
package p // import "hockin.org/p"

Package p is a package.

TYPES

type T struct {
	// Field is a field

	Field int
}
    T is a type

The directive is gone (yay) but there's now a blank line. @ianlancetaylor explains it in #56592 (comment) and acknowledges that it is imperfect (but better than before).
