lines is not equivalent to (splitOn "\n")

λ> Data.Text.lines "\n"
[""]
λ> Data.Text.splitOn "\n" "\n"
["",""]

This surprised me a bit. I think it should be documented at least.

The behaviour of Data.Text.lines is matching Data.List.lines. It would be nice to mention this in documentation indeed.
