Right. I'm just suggesting that source text is better than line numbers
for exact position identification, so I don't see a lot of value in
preserving historical behaviors that change line numbers by one count
one way or another. If some of the PLs used zero-based instead of
one-based line numbers, we'd be looking to standardize that not cater to
their individual idiosyncrasies.
