Re: [PATCH 2/3] blame: refactor porcelain output

> This is in preparation for adding more porcelain output
> options. The three changes are:
>
>  1. emit_porcelain now receives the format option flags
>
>  2. emit_one_suspect_detail takes an optional "repeat"
>     parameter to suppress the "show only once" behavior
>
>  3. The code for emitting porcelain suspect is factored
>     into its own function for repeatability.
>
> There should be no functional changes.
