specify the number of iterations where we use a "strict" Newton convergence criterion using a separate parameter

Browse Source 
that parameter is called "max_strict_iter". This increases the
flexibility of this slightly and it avoids screwing up the default
value for the "max_iter" parameter in the future. The credits for this
patch go to [at]atgeirr for proposing it.
