And here's a v2 that addresses all of the comments except one: Stefan
suggested that --only-existing wasn't a great name. I agree, but I like
everything else less.


  - opts arguments are now const
  - tests that depend on the value of trailer.sign.command now set it
  - the arg_head variable is now moved into the conditional block whewre
    it's used
  - the interpret-trailers manpage has been updated in patch 5 to make
    it clear that "add" and "parse" are the two major modes

  [1/5]: trailer: put process_trailers() options into a struct
  [2/5]: interpret-trailers: add an option to show only the trailers
  [3/5]: interpret-trailers: add an option to show only existing trailers
  [4/5]: interpret-trailers: add an option to normalize output
  [5/5]: interpret-trailers: add --parse convenience option
