df wishlist

[Bruce Dubbs]

It would be helpful to add a --terse option to df such that a user could 
do something like:

DF=$(df -k --terse --output=used $PWD)
Right now I see no method of omitting the header or to collapse the 
spaces between values to a single space.  This can be done of course 
with tools like awk, cut, sed, grep, tail, etc, but would be a lot 
cleaner if done inside df.
