Go 1.19 includes some changes to gofmt which intend to make lists and heading clearer when rendered (https://go.dev/doc/go1.19). This commit is the result of running the new gofmt and manually fixing some of it. This was necessary because the new gofmt assumed lines beginning w/ tabs to start lists or examples. While this is often true in our codebase, we occasionally also use tabs to indent the lines after a TODO or FIXME prefix or in yaml (e.g., excerpts of a snap.yaml). This meant that a lot of the reformatted comments were broken and had to be fixed manually. Signed-off-by: Miguel Pires <miguel.pires@canonical.com>
