While pre-existing in both cases, two nits: There's a stray blank before one
of the commas, and indentation is wrong too.
Furthermore there's no reason to split the format string, especially not
ahead of the \n. Plus line wrapping for the 8 entries[] references could
also be done more evenly.
Since these are all cosmetic, I guess I'll do adjustments while committing:
