oc set env doesn't return a list of objects that can be passed to oc create

[csrwng]

If you run something like:

oc new-app https://myrepo -o yaml | oc set env -f - MYVAR=value -o yaml | oc create -f -

Only the last item in the list is created

Version

oc v1.4.0-alpha.0

Steps To Reproduce

pipe a set of objects through 'oc set env' with -o yaml

Current Result

the set of objects comes out the other end, but not inside a list

Expected Result

the set of objects comes out inside a List so it can be piped to 'oc create'
