(size_trunc_len): align to properly use either IEC or SI prefixes with the unit B (byte).

Browse Source 
Additionally always put a space between number and unit which is
required by the norms.

It is important to note that really small buffers have to be bigger than it
appears because they store bytes and non-Latin scripts need more than one byte
with UTF-8 to encode them, e.g., the string "1023 МиБ" in Russian requires
11 bytes + null terminator.
