After the introduction of atom_type, we can use atom_type to represent the atom type. So modify the parameter type of grab_person() to atom_type, and take use of the characteristics of ATOM_AUTHOR == ATOM_AUTHORNAME - 1 == ATOM_AUTHOREMAIL - 2 == ATOM_AUTHORDATE - 3 to check which author atom type is. ATOM_COMMITTER, ATOM_TAGGER are same too. At the same time, merge the for loop which handles %(creator*) in grab_person() into the previous for loop which handles %(author*), %(committer*),%(tagger*). This can reduce unnecessary traversal of the used_atom list.
