opam config env no longer works on fish with 1.2.1

[talex5]

Seems to need ; at the end of each line:

$ eval (opam config env); ocaml -version
fish: Unknown command 'ocaml'
eval (opam config env); ocaml -version
                        ^

This works:

$ eval (opam config env | sed 's/$/;/g'); ocaml -version
