Phew, it took me a long time to understand how this patch could fix
the bad regexp on some of the examples you provided (the after_stop
field is empty), because I failed to notice that you added the missing
comma.

This looks right to me. Please go ahead an apply (I will rotate the
ChangeLog et al in a moment).
