Do you mean for --include-type=blahfs to display blahfs
along with the default types it displays.
I.e. where blahfs would normally be suppressed
(due to being a dummy file system etc.).

If so, that doesn't seem that useful,
as for that use case you'd probably be more
interested in seeing blahfs in isolation.
