…n, r=brson r? (yes, the review request is back, now that I got it building against incom... I mean master!) (Attempting to port from orphaned pull-request #6764 ) Fix for #3961. Also includes a test case to illustrate the issues. (All of the entries that say "should align" should align with each other, and the four lines near the end that say "compare _" for _ in {A,B,C,D} should line up with each other.) Before applying this change set: -- the "(should align)"'s are all over the place, and the form/line feeding spaces are not cut out as one might or might not expect. -- compare B and D do not match A and C. (To be honest, its hard to really say what the right behavior is here, and people who are expecting a particular behavior out of a pretty printer in these cases may well get burned.)

Disable `vec_box` when using different allocators Fixes rust-lang#7114 This PR disables the `vec_box` lint when the `Box` and `Vec` use different allocators (but not when they use the same - custom - allocator). For example - `Vec<Box<i32, DummyAllocator>>` will disable the lint, and `Vec<Box<i32, DummyAllocator>, DummyAllocator>` will not disable the lint. In addition, the applicability of this lint has been changed to `Unspecified` due to the automatic fixes potentially breaking code such as the following: ```rs fn foo() -> Vec<Box<i32>> { // -> Vec<i32> vec![Box::new(1)] } ``` It should be noted that the `if_chain->let-chains` fix has also been applied to this lint, so the diff does contain many changes. changelog: disable `vec_box` lint when using nonstandard allocators
