fix factoring macro

_update_state_for_ident_list was not always called with the same last parameter.
Add a boolean parameter to UPDATE_STATE_FOR_IDENT_LIST_AND_JUMP_ON_ERROR in
order to relay it to _update_state_for_ident_list like the original unfactored
code did.  I do not fully understand this part, but did not mean to change it.
