tutle output for lists of blank nodes

[Élie Roux]

I'm currently looking more closely at Jena's ttl output and I see things
like:

bdr:G844  a             :Place ;
        :placeEvent     [ a           :PlaceFounded ;
                          :onOrAbout  "13uu/17uu"
                        ] ;
        :placeEvent     [ a                       :PlaceFounded ;
                          :onOrAbout              "1187" ;
                          :placeEventAffiliation  bdr:TraditionTest
                        ] ;

but I don't really understand why it is not serialized as

bdr:G844  a             :Place ;
        :placeEvent     [ a           :PlaceFounded ;
                          :onOrAbout  "13uu/17uu"
                        ] ,
                        [ a                       :PlaceFounded ;
                          :onOrAbout              "1187" ;
                          :placeEventAffiliation  bdr:TraditionTest
                        ] ;

which would seem more clear to me... is it on purpose? If not I can make
a PR for it.

Thank you,
