I don't see any reason not to re-enable the warning if we make row
detection programmatic, it would only appear then if something wonky
is going on (and if something wonky / out of the norm. is going on
with my terminal, I -would- want to see the warning).
In my opinion the best thing to do would be to firstly check the
environment for ROWS (I think?) and if those are not present,
determine rows in the same fashion as `stty size`, and if that fails,
fall back to using DEFAULT_TOPN.
I have no opinion on the default value of DEFAULT_TOPN if the above is
done, but 17 is probably quite reasonable, as most terminals default
to 24 rows.
