Closing. There is no bug here. cmd _always does_ output new line after every command. If you do not want that - do not use it.
Why didn't cmd output new line in Wine 1.1.35 and does that in Wine 1.1.36?
Probably http://source.winehq.org/git/wine.git/?a=commitdiff;h=cc72c4d346fa0d61ec19f9..., which was needed to match windows behavior.
