Using console mode of Yace, it will even show the whole line:

   221150   0.529  Mat17 32.  1.Ke2 a3 2.Kd3 a4 3.Kc4 a5 4.Kb5 Kh8 5.Ka6 Kg8
                              6.Kxa7 Kh8 7.Ka6 Kg8 8.Kxa5 Kh8 9.Kxa4 Kg8
                              10.Kxa3 Kh8 11.Kb4 Kg8 12.a4 Kh8 13.a5 Kg8
                              14.a6 Kh8 15.a7 Kg8 16.a8=Q Kh8 17.Qxf8# {1001}

Many GUIs will cut long PVs at some point.
