This bit seems unnecessarily vague:
Depending on the requested combination of start, stop, and step, it is
possible to return zero rows.
I think you can provide a precise specification without losing
simplicity of explanation. Maybe something like
When step is positive, zero rows are returned if start > stop.
Conversely, when step is negative, zero rows are returned if
start < stop. It is an error for step to be zero.
... and then carry on with the examples, which seem fine (although
the one showing the error for step=0 might be thought redundant
with the text).
