At first, I wanted to avoid of having a global variable but I was not
sure if I could add my error structure to an existing structure and I
did not want to overload the callchain with a new parameter.
So now, I attached my structure to struct unpack_trees_options.
I also corrected all the style errors and the following remarks.
Thanks.
