status: show in-progress info for porcelain v2

Porcelain v2 format is intended to be extendable. So we add in-progress information unconditionally to the branch information (in case that is shown at all). Note that - in contrast to the short status info - we add all available information in case multiple operations are in progress, and we do so by outputting one line per operation.
