AWS CloudFront access logs are stored in S3 as TSV files (one per hour
per CF node) with a two-line header comment where the first line is the
version and the second lists the fields (but not in a form useful for
HEADER MATCH).
Although not useful for the above format, and not intended to derail or
bloat the proposal in this thread, would it be useful to have a mode
that combines skip and match? I.e. skip N lines, then check the fields
in the one after that against the target columns.
