So, I haven't quite worked out what this *is* doing, but on further reflection,
it seems like "-f" should definitely relate to behavior which iterates over
all filesystems.  i.e. without -f, non-xfs filesystems are skipped; with -f,
"foreign" filesystems are included.  That was my main concern.

But if an xfs_quota command is pointed directly at a non-xfs filesystem,
I'm not sure what's best.  Assume the user intended it, and operate on
that fs w/o needing -f?  Or require "-f" for consistency?  What do you think?

And, we can specify multiple mount points to operate on, i.e.

xfs_quota -c "foo" /mnt/ext4 /mnt/xfs

so ... I guess I don't know if that should require -f or not.  principle of
least surprise?  Keep old behavior of ignoring the non-xfs mount?
