* add test for importing empty .xsh file * test: empty lines do not get appended to history prompt-toolkit needs its own test outside of test_base_shell.py because it uses a custom _push() method * fix: do not append empty/comment-only input to history Adds a compile_empty_tree argument to Execer.compile() By default, the argument is `True`, and `compile()` returns a compiled `pass` statement for comment-only input. When the argument is `False`, `compile()` returns `None` for comment-only input. The base shell and prompt-toolkit shell use `compile_empty_tree = False` so that they get `None` as the compiled code and don't append the command to the history. * add news * fix tests
