Hmmm... from the lsof man page:

    When -f is specified by itself, all path name  arguments  will
    be  taken  to be simple files.  Thus, for example, the ``-f --
    /'' arguments direct lsof to search for open files with a  `/'
    path name, not all open files in the `/' (root) file system.

The existing -l, -p, and -t are compatible with previous lsof
implementations. (We don't seem to be doing the -p ^pid thing that
_excludes_ pids, but what _is_ there is compatible.) But this looks like
a new definition of -f? (It's hard to tell because the lsof man page is
so busy...)

How would you get the other lsof to filter the output this way?
