The new thresholds format specify a unit option (where it makes sense;
check_disk knows the unit is bytes) and a prefix (SI prefix, including
the binary ones like Ki, Mi...), but the idea is that the prefix should
be used for printing only and performance data should be in double
format without any prefix.

It will however be easy to add extra parameters to alter the
functionality, so that is someone needs backwards-compatible output we
could add an option for that.
