Different behavior of df

[Javier Viguera]

Hi all,

I have seen that the behavior of "df" command has changed since previous 
version of busybox and it is also different from coreutils-6.10.

It works OK with no arguments, but when you pass as argument the root 
file system (/) it gives no output on newer busybox.

Tests:

> $ ./busybox-1.14.1 df /
> Filesystem           1K-blocks      Used Available Use% Mounted on

Is it a bug that new busybox (1.14) gives no info in this case?

Attached my .config file.
