yes, I'm sorry I didn't take care of this sooner.
I don't think there's value in printing the "(null)" line; I think maybe my
suggestion from that old thread might be best:

Or now that I think about it - projid 0 is the default project quota, right?
Assuming that's correct, perhaps we should conditionally print the line,
changing "(null)" to "default", printing it only if a default quota is
set (i.e. not all zeros).
