fix 00 byte after values when --human is not set

Since 33557c3d: Display a percent sign after the value when --human
option used in non --human mode the output has an exta spurious '0'
byte.

That is printed by the percentage unit being set to char u = '\0'.
But that is not "nothing" it is literally byte "00".

This change only calls printf with a literal % when needed.

Fixes 165
