Closures did not have their bounds printed at all, nor their lifetimes. Trait bounds were also printed in angle brackets rather than after a colon with a '+' inbetween them. Note that on the current task::spawn [1] documentation page, there is no mention of a `Send` bound even though it is crucially important!

Don't warn on proc macro generated code in `needless_return` Fixes rust-lang#13458 Fixes rust-lang#13457 Fixes rust-lang#13467 Fixes rust-lang#13479 Fixes rust-lang#13481 Fixes rust-lang#13526 Fixes rust-lang#13486 The fix is unfortunately a little more convoluted than just simply adding a `is_from_proc_macro`. That check *does* fix the issue, however it also introduces a bunch of false negatives in the tests, specifically when the returned expression is in a different syntax context, e.g. `return format!(..)`. The proc macro check builds up a start and end pattern based on the HIR nodes and compares it to a snippet of the span, however that would currently fail for `return format!(..)` because we would have the patterns `("return", <something inside of the format macro>)`, which doesn't compare equal. So we now return an empty string pattern for when it's in a different syntax context. "Hide whitespace" helps a bit for reviewing the proc macro detection change changelog: none
