You aren't missing anything. The philosophy here is that this
reformatting, which only applies to doc comments, will ensure that the
comment looks acceptable as a comment, as HTML, as Markdown, and as
plain text. That necessarily restricts the kinds of things that can
appear. The exact docs are at
https://go.dev/doc/comment.
If you give us more details perhaps there is some common ground
available. In particular, a sequence of lines where each line is
indented will be treated as a code block, and not reformatted.
