Overview: When writing tutorials or code documentation, it's helpful to be able to paste a git diff output, which can highlight added lines in green and deleted lines in red.

For example, I might want to paste:

 - (void) myMethod {
+    [self doSomethingNew];
-    [self noLongerUsed];
 }

However, right-clicking on the diff and pressing "Copy" doesn't let me include the plus and minus symbols.

I recommend adding a "Copy with Diff Markers" option. I understand this is a minor use case, so perhaps it should only be visible when holding down the option key.
