This is a port of the following commit from the Linux kernel:

commit 29ee1b0c67e0dd7dea8dd718e8326076bce5b6fe

    checkpatch: ignore email headers better

    There are some patches created by git format-patch that when scanned by
    checkpatch report errors on lines like

    To: address.tld

    This is a checkpatch false positive.

    Improve the logic a bit to ignore folded email headers to avoid emitting
    these messages.
