The documentation says:
> The writable register systat contains the return value of the system()
> function executed by the last sy request.
When executing the following document with `nroff -U filename.roff`, the
output is: `0`, eventhough it should be `1`.
```roff
.sy /usr/bin/false
\n[systat]
```
