The un-compression of MM rests is an intentional feature of `jianpu10a.ly`. You should contact the author to add a command that switches compression of MM rests on and off. Below is a trivial patch to enable MM compression. Note, however, that this also disables conversion of `R1` to '0 0 0 0', which is probably not wanted. In other words, I suspect that more tinkering is necessary to get a solution that really fits current jianpu usage.
