[PATCH v3 0/4] clarify meaning of --signoff & related doc improvements in describing Signed-off-by

[ Note that there were competing v2's of this patch series, one from me and
  one from Junio.  Sorry about that; I had missed Junio's from Sunday. ]

I believe this patch series now addresses all the issues raised in the discussion.

  * [1/4] is unchanged from Junio's v2 and is the preparatory cleanup.

  * [2/4] remains unchanged textually since I originally posted it and Pfeff
    signed off.

  * [3/4] is unchanged from Junio's v2 and is his clarification for what
     Git's --signoff means.
     
  * [4/4] is a rework of a patch from *my* v2.  It takes into account Junio's
    comments about preferring the word "trailer" and leaving off the ':'
    whenever possible when discussing Signed-off-by.

For reference:

        v1: https://lore.kernel.org/git/20201015215933.96425-1-bkuhn@sfconservancy.org/
