config: remove peeked + expanded line log entries

The peeked and expanded line log entries were useful during the switch
to generic code blocks and subcommands. However, it has been a while
since those were introduced and the log entries are no longer helpful
for any remaining issues with config parsing. Instead of keeping them
as clutter in the log, they can just be removed.
