Subject: [PATCH] Make sure we detect if start >= numlines so we can deal with
that properly
for some apparent reason the compiler didn't like the while loop condition edit on its own (it complained about inline failures for P_MobjReadyToTrigger for some reason), so I had to add that extra bit above the while loop... and it was happy again, huh
