Hi Karel,

thanks for the suggestion.

The idea was to bring the basic support for variable output
into df first, and then I think the way is open for further
discussions. E.g. handling different scale factors for the
columns may be interesting - something like this:

  df --output=target,used/1M,iused/1K

I'm not sure if df should go any further this way, as such
processing is usually up to the caller.
We'll see.

Have a nice day,
