pdftex and luatex 0.95 give an interline penalty of 300 (= club + widow)
...\glue(\rightskip) 0.0
..\penalty 300
..\glue(\baselineskip) 7.69446
but 0.98.4 gives a penalty of 156 ??
...\glue(\rightskip) 0.0
..\penalty 156
..\glue(\baselineskip) 7.69446
ah, indeed, the 6 is the internal register number of widow_penalty:
linebreak.w: line 186
(d ? display_widow_penalty_par :
widow_penalty_par),
(so add _par) ... a side effect of normalizing all kind of register
access so that one got lost
