Why not make subdir_nr unsigned (like in for_each_file_in_obj_subdir()), and
get rid of this first check?

Using unsigned char for subdir_nr would allow removing the second check as
well, but might hide invalid values in implicit conversions, I guess.

Showing the invalid value (like in for_each_file_in_obj_subdir()) would make
debugging easier in case the impossible actually happens.

About here would be the ideal new home for ...
