Yeah, z doesn't reliably translate to int64 either, so it's only useful
when the number you're trying to print is a memory object size.
I don't really see how controlling snprintf is enough to get somewhere
on this. Sure we could invent some new always-64-bit length modifier
and teach snprintf.c about it, but none of the other tools we use
would know about it. I don't want to give up compiler cross-checking
of printf formats, do you?
