I'd like to notice that in this extension we have mistake in notation of rests. As I know the correct notation is subsequently:

...so we have equantion:

+ | = |

In present MediaWiki version of LiliPond is wrong notation, because is subsequently:

So in point of MediaWiki's view it is at the moment so...:

+ | = |

Could anybody correct this failure in **this extentension**?
Thanks in advance!
