Thanks. Please add all the long options from the 'fi df' subcommands as
well. As the subcommand is not entierly space & size oriented, I'd like
to keep the single letter options unallocated for now.
I will use --human to subsititute -h option. Should I add other long
options like --kbytes --mbytes --gbytes --tbytes --si --iec?

I will merge need_print and human_readable into one variable.

I wiil try to remove switch.
