Adding another R1 to each group makes clearer what happens:
restNumberThreshold is consulted at the moment the rest ends, not when
it starts. Recording it at the time of the rest start would be
additional work. There is a reason many settings like these are
actually grob properties rather than context properties: that way they
are recorded at grob creation time. For a setting that decides whether
or not to even create a grob, that is a bit tricky but it could be
considered a property of the rest itself rather than of the rest number.

As it’s fairly common, recommended by Gould, and—depending on house style for
longer measures—sometimes necessary to have single measure MMRs marked with a
“1” in orchestral parts, it should be documented how this can be achieved:
```
\set restNumberThreshold = 0
```
The default seems to be “unset” but in multi-measure-rest-engraver.cc it is
hardcoded to 1; you won’t find this value in engraver-init.ly.
