Run 2to3 and pick the sensible suggestions.
Import print_function and absolute_import so 2.6 can work.
There has never been a curses.wrapper module according to 2.x and 3.x
doc, only a function, so "import curses.wrapper" is not correct. It
happened to work because 2.x implemented a (undocumented) module.
We only need to import curses to make curses.wrapper available to
pygrub.
