For example, git log --pretty="%(trailers:key=Signed-Off-By,separator=%x2C )" will output all the trailers matching the key and seperates them by a comma followed by a space per commit. Add similar functions, match_atom_arg_value() match_atom_bool_arg() in ref-filter. There is no atom yet that can use these functions in ref-filter, but we are going to add a new %(describe) atom in a subsequent commit where we parse options like tags= or match= given to it.
