"git interpret-trailers" has been taught a "--parse" and a few other options to make it easier for scripts to grab existing trailer lines from a commit log message. * jk/trailers-parse: doc/interpret-trailers: fix "the this" typo pretty: support normalization options for %(trailers) t4205: refactor %(trailers) tests pretty: move trailer formatting to trailer.c interpret-trailers: add --parse convenience option interpret-trailers: add an option to unfold values interpret-trailers: add an option to show only existing trailers interpret-trailers: add an option to show only the trailers trailer: put process_trailers() options into a struct
