[PATCH] Options to set fixed unit for `filesystem df`

[Nils Steinger <nst@voidptr.de>]

Currently, `btrfs filesystem df` uses the pretty_size() function, which
automatically selects a unit to display a size in, e.g. 1024 bytes will be
displayed as "1.00KiB".
This makes parsing the output of `filesystem df` unnecessarily hard, so I've
added the options -b, -k, -m, and -g to get the output in bytes, kibi-, mebi-,
and gibibytes respectively.

Nils Steinger (1):
  Add options to use a fixed unit for `filesystem df` instead of
    determining it automatically.
