Fix on multiline comment with tab indentation

[thorger]

What version of this package are you using?
https://standardjs.com/demo.html
same behaviour on local version

What happened?
Code with multiline comment tab indented:

    /**
     * some comment
     * 
     */

after using --fix returns:

/**
     * some comment
     */

removing only first tab and not reformatting / fixing next 2 lines.
Running 'npx standard' highlight those 2 lines as breaking eslint rules

What did you expect to happen?
Apply correct indentation to multi-line comment, removing tab characters and populating with spaces if required.
Currently, issue is highlighted but not fixed with '--' fix parameter.
