The most problematic rule is "don't reformat code you don't touch",
so the formatter needs to limit it's scope.

Not only to the lines touched, but "things touched", see:

-	int var = ...;
+	int val = ...;

	// ...

-	err = long_call_a_bit_wrong_perhaps_too_long_line(var, other);
+	err = long_call_a_bit_wrong_perhaps_too_long_line(val, other);

so, the rename of poor "var" to better (but same length) "val",
you don't want to break long_call_a_bit_wrong_perhaps_too_long_line()
into multiple lines here
