I can help look into this, but how is it different from #5630? Are there ever situations where a trailing end-of-line comment isn't handled as a line suffix?

#5630 is only about adding the reserved_width field to LineSuffix but without changing the formatting yet (always initialise it with 0). This issue is about changing the default to the actual comment with.
