[PATCH v2 1/5] trailer: ignore comment lines inside the trailers

[Christian Couder <chriscool@tuxfamily.org>]

Otherwise trailers that are commented out might be
processed. We would also error out if the comment line
char is also a separator.

This means that comments inside a trailer block will
disappear, but that was already the case anyway.
