This is pointless --- the function is already intended only for
debugging considerations, and anyone who needs it can be assumed capable
of ANDing with a bitmask or whatever he needs to do to inspect the
values. I don't see anyone asking for pretty display of cmin, say,
and yet that's certainly not that easy to interpret either.
As for masks plural, I'd be inclined to merge them into one 32-bit
result --- the distinction between flag bits in infomask and infomask2
is at this point entirely historical.
