Would the following be acceptable:
1. remove "--to=<NUMBER>" option
2. surplus characters following immediately after converted number trigger a 
warning (error?), 
  except if the following characters match exactly the "suffix" parameter.


Regarding "--format":
The implementation doesn't really use "printf", so "%d" isn't directly usable.
One option is to tell the user to use "%s" (instead of "%d"), and we'll simply 
put the result of "human_readable()" as the string parameter in vasnprintf - 
this will be flexible in terms of alignment.
Another option is the remove "--format" option, and replace it with "--padding" 
or similar.

Regarding grouping (thousands separator):
This only has an effect when no using "--to=SI" or "--to=IEC", right?
Perhaps we can add a separate option "--grouping", and simply turn on the 
"human_grouping" flag? (easy to implement).
