There is no difference for "root" directive. Actually, nginx deletes
trailing slash from "root" directive because $request_file_name is
$document_root$uri", and $uri has slash as first character.

But the trailing slash is important for "alias" directive, because
"alias" literally replaces location part of URI:

location /dir/ {
     alias  /path/to/;
}

/dir/file > /path/to/file
