The create-patch-request script creates patches as replies to a cover
letter, in the form of an email thread. If further revisions are sent to
the mailing list without referencing to the first revision, these new
revisions are not identified at the mailing list as part of the original
thread, but as a new thread instead.
This change adds the "[-t in_reply_to]" option, where "in_reply_to" is
the original cover letter's Message-Id, so this reference is added
to the new cover letter to ensure the thread continuity.
