I actually agree that there's a problem there. What I find pretty dubious
is the claim that this patch will fix it.
If we could see our way to recognizing help/quit/exit on a line by
themselves even when there's data in the query buffer, the argument
that we've improved matters for novices would be *far* stronger.
However, given that this is legal, fully-spec-compliant SQL:
select a, b
exit
from mytable;
I'm not sure how we could get away with that. Would it pass muster to do
that only when isatty(stdin)? Other ideas?
