I was looking at disk usage today and found that being able to output the specified file names in the display would be useful. Consider the new 'Name' column in:

$ df --o=target,name,pcent /var/* Mounted on Name Use% / /var/cache 71% / /var/lib 71% / /var/local 71% /run /var/lock 1% / /var/log 71% /run /var/run 1% / /var/spool 71% /var/tmp /var/tmp 71% / /var/www 71%

The attached implements this. Worth adding?

One caveat is that the Name is '-' if you don't specify any arguments to df, so therefore if you output all columns by using --output without a parameter, you'll get a redundant column. I suppose one might suppress this column in that case?

thanks, Pádraig.
