Lilylib: When formatting the options help, use only one level of indentation

We tweaked the IndentedHelpFormatter to not indent the headings at all (even if we have
nested groups), so it does not make sense to indent the options themselves, either.
Thus, we now have either no indent or exactly indent_increment.
