cmd/gofmt: allow same level indent for block comments

[dsnet]

Given the following code:

/*
someDisabledCode()
*/

It will be reformatted as:

/*
	someDisabledCode()
*/

(notice the indent it injects)

This is frustrating for users who need to maintain patches since it means that there is now a potentially massive diff when trying to comment large blocks of code in a patch.

Would it be possible for gofmt to stop trying to indent everything within the block comments?

@dsnet Yes, it would be possible :-)

It was probably a mistake to try to "adjust" comments in any way with gofmt, but it also has been like this for > 10 years. We could try to just leave comments alone. It shouldn't have an effect on existing code since it would simply remain untouched.

\cc @rsc for another opinion.

Yep, and every year, I've probably been annoyed by this behavior. It took till now for me to file an issue about it ;)

This gets a thumbs up from me too. Though I have to admit, I only ever use /* comments to comment out chunks of code without affecting the diff too much (modulo this issue).

This also frustrates me, because additional indent destroys "blame" for all commented lines.

Looking forward for the fix)
