>Description:
	When mounting nfs filesystems, the long pathnames causes df listings
	to look real ugly and are difficult to read. Example:

my40:/usr/src/bin/df >df
Filesystem                         512-blocks     Used    Avail Capacity  Mounted on
/dev/sd0a                               56542    27424    23462    54%    /
/dev/sd0d                               56542       12    50874     0%    /tmp
/dev/sd0e                               56542     2408    48478     5%    /var
/dev/sd0g                              835166   598568   194838    75%    /usr
my28:/e/local                         1168204   904378   147006    86%    /usr/local

my3:/SunOS4/usr/local                 3846624  2405638  1056326    69%    /tomat

This looks nicer if the lines splits when long mounts (as SunOS):

my40:/usr/src/bin/df >./df
Filesystem         512-blocks     Used    Avail Capacity  Mounted on
/dev/sd0a               56542    27424    23462    54%    /
/dev/sd0d               56542       12    50874     0%    /tmp

>How-To-Repeat:
	Mount a long directory from somewhere and type df :-)
>Fix:
	This will fix parts of it; but it is ugly and could be done cleaner:
