Groups with comments below single var declaration are unexpectedly formatted

[ndrpnt]

This is more of a question. The current behavior:

var (
	foo = "foo"
	// bar = "bar"
	// baz = "baz"
)

var foo = "foo" // bar = "bar"
// baz = "baz"

Is it desired ? I would expect gofumpt to either keep the parentheses and comments untouched, or to format this way:

var foo = "foo"
// bar = "bar"
// baz = "baz"

This is also consistent with the behavior when adding an inline comment:

var (
	foo = "foo" // foo
	// bar = "bar"
	// baz = "baz"
)

var foo = "foo" // foo
// bar = "bar"
// baz = "baz"

I have no strong opinion on the matter, I just found it surprising. Feel free to close if this is intended

The grouping seems right, even if it looks off - the commens are just comments, so they aren't considered as declarations. And a lone grouped declaration loses the grouping as it's overkill.

In your first example, // bar = "bar" should not become an inline comment, though. That's a bug.
