This series is based on the initial series [1], notably the v4 version of
patches 10-16 as suggested by Christian [2]. This version addresses the
review comments for those patches, namely the avoidance of (temporary) test
breakages.

The central idea is to unify the functions format_trailer_info() and
format_trailers() together (preferring the name of the latter), so that both
the interpret-trailers built-in and format_trailers_from_commit() can call
the same format_trailers() function, while maintaining feature parity.

  format_trailer_info(): use trailer_item objects

  trailer: begin formatting unification
