In all divisions, you should write “1024.” to have inexact numbers.  It
turns out that currently ~h does that for you, but it’s safer to do it
upfront.

With this change you can push right to master!

In the future we should probably have a ‘number->size’ (the dual of
‘size->number’ in (guix ui)) that would take a byte count and return a
string denoting the size in a human-friendly way (as KiB, MiB, or GiB).

Thanks,
Ludo’.
