No. Custom format specifiers that take arguments will confuse the heck
out of gcc's format-checking warnings. There is no way that saving
a bit of ugliness is worth that. Just do format_memory_amount(foo)
and print it with %s.

Probably yes. But it strikes me that the additional numbers printed for
Sort nodes might be bogus in multiple-loop cases too; what about that?
