----------------------------------------
This patch enables "human-readable" printing of inodes count when df(1)
is called with both -h and -i flags. This is similar to what can be
found on FreeBSD df(1) or GNU df(1).
The code has been adapted from FreeBSD's df(1).

Functions local to the module were also made static to be compliant with
style(9).

Example output:

Now:
