Wouldn't it be better to output the exact buffer size,
rather than an approximation?  Usually it's better to
output more information, rather than less, to help
debug problems more precisely.

One way to do this would be to output the same string
that the user specified: if the user says "bs=3EiB" then
output "3EiB" in the diagnostic.  That would be exact,
and would be a bit friendlier than "3458764513820540928 bytes".
Or, we could output both, as in "3EiB (3458764513820540928 bytes)",
where the first is the string and the second is the integer that
we converted it to.
