Can Git diff parameters improve source code change alignment?

Adding annotated functions to an existing source file produces mis-aligned diffs. For example, consider adding the provideNewThing method:

@Provides
Foo provideFoo() {...}

@Provides
NewThing provideNewThing() {...} 

@Provides
Bar provideBar() {...}

Running git diff on the command line will show:

     @Provides
     Foo provideFoo() {...}

     @Provides
+    NewThing provideNewThing() {...}
+
+    @Provides
     Bar provideBar() {...}

This is not ideal. It appears I've introduced the @Provides annotation to provideBar. A closer look shows otherwise, but it's easy to miss.

Ideally there is a git diff <some-options> which outputs:

     @Provides
     Foo provideFoo() {...}
+
+    @Provides
+    NewThing provideNewThing() {...}

     @Provides
     Bar provideBar() {...}

Is this possible?
