Best, Mike

_ENCODE_FILE_NEW is now supported and untagged files are also now supported

[MikeFultonDev]

@IgorTodorovskiIBM should this be closed now?

Another issue also mentions this. I think we should re-investigate how auto-detect works and see if we can do better?
But this is a zoslib issue not vim I think?

@IgorTodorovskiIBM @mgrossmann @gngrossi thoughts?
