Minor bug in df

[Luke Kendall]

The column formatting of the plain "df" output is misaligned, making it
hard to read.  Same is true for -P option.  For example:

: /home/data/audio; df
Filesystem           1K-blocks Used Available Use% Mounted on
/dev/md0              12389244   5420288   6339616  47% /
varrun                  517924       180    517744   1% /var/run
varlock                 517924         0    517924   0% /var/lock
procbususb               10240       184     10056   2% /proc/bus/usb
udev                     10240       184     10056   2% /dev
devshm                  517924         0    517924   0% /dev/shm
lrm                     517924     18132    499792   4%
/lib/modules/2.6.17-11-386/volatile
/dev/hda1             46082420  19358248  26724172  43% /C
/dev/hda2              2044272    152512   1891760   8% /D
/dev/md2             119623076  71464176  42082324  63% /home
/dev/md1              12389244   5664076   6095828  49% /mnt/alt-slash

It should be:

: /home/data/audio; df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/md0              12389244   5420288   6339616  47% /
varrun                  517924       180    517744   1% /var/run
etc.

df -h output is also misaligned, but not as badly.  E.g.:

: /home/data/audio; df -h
Filesystem            Size Used Avail Use% Mounted on
/dev/md0               12G  5.2G  6.1G  47% /
varrun                506M  180K  506M   1% /var/run
etc.

: /home/data/audio; df --version
