I don't like '--just' because it does not tell what this is about. One
might confuse it with something regarding (left- or right-) justification.

How about --list-type? I'd say the name should contain 'type' and
something to differentiate it from '--file-type'.

Anyway, ls --file-type | grep _might_ work most of the time, but would
become difficult with e.g. spaces or newlines in a file name, thus I'd
say this functionality looks useful.
