Errors returned by Reader contain the line where the Reader originally encountered the error. This can be suboptimal since that line does not always correspond with the line the current record/field started at. This can easily happen with LazyQuotes as seen in #19019, but also happens for example when a quoted fields has no closing quote and the parser hits EOF before it finds another quote. When this happens finding the erroneous field can be somewhat complicated and time consuming, and in most cases it would be better to report the line where the record started. This change updates Reader to keep track of the line on which a record begins and uses it for errors instead of the current line, making it easier to find errors. Although a user-visible change, this should have no impact on existing code, since most users don't explicitly work with the line in the error and probably already expect the new behaviour.
