Enable whitespace for diff in NetBeans

I was working on a project and changed some files. NetBeans showed me several files had been modified compared to the latest versions from the versioning control system.

We can disable this so we can see all the changes to a file, even whitespace differences. We need to go to "Tools | Options | Miscellaneous | DIff". Now we can uncheck the checkbox "Ignore Whitespaces":

The diff viewer will now show the extra spaces added to line 12:
