Eh?

The core algorihtm for printing out a number in human readable units;
that's definitely worth a test, and I assume there already is one - I
didn't touch that.

But whether or not the units suffix has a space, or a B suffix? That's
not going to break in subtle ways; that either works or it doesn't.
