These perfeclty good patches from 2014 weren't picked with no good reason.

These are safe no-op changes, but that does not mean they are good patches. It goes against Documentation/CodingGuidelines to bring it back again now, which is a good enough reason not to look at them.

They are not good patches because they are no-op, they are good changes because they correct the flow of the code to match the flow in which most people think.

  18 is younger than Mary
is not a sentence most people would agree make sense.

These are not style issues. Refactoring code to make it easier to understand goes beyond style.

Refactoring this:
	static int is_same_remote(struct remote *remote)
	{
		struct remote *fetch_remote = remote_get(NULL);
		return (!fetch_remote || fetch_remote == remote);
	}
	int same_remote = is_same_remote(remote);
To this:
	int same_remote = remote == remote_get(NULL);
Is more than just style.

But suit yourself. Sooner or later somebody is going to fix these glaring mistakes. And they are mistakes [1].

  Yoda conditions are widely criticized for compromising readability by
  increasing the cognitive load of reading the code.
Cheers.
