Sorry for coming late to this thread. In sshd(8), where the 'command'
syntax is described, the following passage is of significance:

    The command is run on a pty if the client requests a pty; otherwise
    it is run without a tty.  If a 8-bit clean channel is required, one
    must not request a pty or should specify no-pty.

I think that the cause of end-of-line conversion is that ssh thinks
it is providing output to a terminal which requires it. I use no-pty
myself and I have not had problems with end-of-line conversion.
