Is it true that Nietzsche's philosophy was basically bastardised by his sister?

I've read that, after his death, Nietzsche's unpublished manuscripts fell into the hands of his sister Elisabeth, who then edited and published them herself. However, apparently she edited out everything he said against nationalism and antisemitism for the purposes of her German nationalist agenda. It was this version of Nietzsche that became popular in Germany and has been blamed for being one of the main inspirations for Nazism.

So how much did Elisabeth change and when did these changes become known? Could Nietzsche still be interpreted as supportive of Nazi ideology without her editing?

It's really only one "book" (The Will to Power). The rest of the books are authentically Nietzsche, for better or worse, and "The Will to Power" doesn't really encapsulate complete thoughts, at least none that aren't expressed better in other books. 

Nietzsche would likely *not* have supported the NSDAP. That's not to say he wouldn't have been sympathetic to some fascist ideals about strength, for example, but he would have been against the collectivization and standardization of Naziism and the oppression of art and artists.
