Hi Pál (besides, are you Pál Benkő the chess master?)

Thanks for this nice review.

It can be something else.  Some recent editors are also using half and
quarter rests.
One may also want to only have whole rests, so I guess we don't have to
hard-code -3.
I don't honestly know if this has to be range or if bounds would be
enough.
I solved the issue I mentioned in the last comment, so that church rests
only pick duration logs from usable-duration-logs.

I applied the other changes.

Thanks again,
Bertrand
