worlddump: Use __future__ print_function
Commit e7361775c112e32ea517eddc344641897d273d25 changed the code to
use Python 3 style print function, but when doing 'print()' in Python
2.7 it would print '()':
>>> print()
()
Import the __future__ print function so that a blank line will be
printed as expected. This will now work the same in Python 2 & 3.
