Hello,

I thought about that, but since whitespace-cleanup generally applies clean-up according to white-space style, I thought it was simply an oversight that it doesn't apply a fix when it is set to highlight missing end-of-file newline.

Adding a separate way to configure this removes the simplicity of configuring your preferred whitespace-style as a single option.

However, If you still disagree I can make another patch somehow maintains the old behaviour as the default, so just let me know.

Thanks,
Björn
