According to this discussion, there is an issue with nice(1) documentation, which the patch was trying to emulate:
> EXIT STATUS > ... > Otherwise, the exit status of nice shall be that of utility. Which is incorrect, since 'nice' doesn't exit in this case at all, just like 'doas'. Perhaps this line should be omitted, or perhaps removing 'of nice' (or some other rewording) would make it more accurate while still being helpful to any user who may not know the full implementation details. In any case, doas(1) and nice(1) are documented inconsistently for the same behavior.
