| Hmm, like it. Something along the line of:
| 
| $ dd if=/dev/zero of=/tmp/foo msgfmt=quiet
| 1+0 records in
| 1+0 records out
| $ dd if=/dev/zero of=/tmp/foo msgfmt=human
| 1+0 records in
| 1+0 records out
| 1073741824 bytes (1,0 GB) transferred in 15.701 secs (65 MB/sec)

Sure, ideally you could have a formatting string too, so that you output
only the things you need surrounded with the strings you want:

For example the default format could be:

%I+%i records in\n
%O+%o records out\n
%b bytes transferred in %s secs (%p %u/sec)\n
