If you use try_files with fastcgi_split_path_info, do not try to set
PATH_INFO with $fastcgi_path_info directly as it will be empty.

If PATH_INFO is not set (as it might not be required like you point it out)
and stick with the $fastcgi_script_name of the split directive, then the
PATH_INFO 2-lines trick is indeed useless but the rest is correct and
recommended.
