This uncovers a problem in il/il_aux.c: it passes 3 arguments to getlines(), but the function expects 4 arguments. I add FALSE as the 4th argument. TRUE would fill in the list of mesregs. IL uses mesregs during phase 1, but this call to getlines() is in phase 2. TRUE would leak memory unless I added a call to Ldeleteset(mesregs). So I pass FALSE. Functions passed to go() now have a `void *` parameter because no_action() now takes a `void *`.
