Prevent crash when macro is in different file
This was caused by a macro in a different file.
The `target.span` was be in the file of the macro definition and the
`item.span` in the file of the calling code.

3373fa97e2 Add third variant to {pub_,}enum_variant_names examples
The default value for `enum-variant-name-threshold` is 3, so the old examples (which only have two enum variants) don't actually trigger the lint by default.

Handle non-trivial nil closures
`reduce_nil_closure` mixed together a) 'is this a nil closure?' and b) 'can it
be reduced to a simple expression?'. Split the logic into two functions so we
can still generate a basic warning when the closure can't be simplified.

Fix useless_format false positive with macros
Clippy was issuing a warning when `format!` was used inside a macro.
That's a problem because macros have different syntax and can be outside
the control of the user.

This skips the `useless_format` check if the `format!` call is inside a
macro.

Move empty_line_after_outer_attribute to nursery
From the clippy side it's difficult to detect empty lines between
an attributes and the following item because empty lines and comments
are not part of the AST. The parsing currently works for basic cases
but is not perfect and can cause false positives.

Maybe libsyntax 2.0 will fix some of the problems around attributes but
comments will probably be never part of the AST so we would still have
to do some manual parsing.

Fix false positive in empty_line_after_outer_attr
Before, when you had a block comment between an attribute and the
following item like this:

```rust
\#[crate_type = "lib"]
/*

*/
pub struct Rust;
```

It would cause a false positive on the lint, because there is an empty
line inside the block comment.

This makes sure that basic block comments are detected and removed from
the snippet that was created before.

Fix false positive in empty_line_after_outer_attribute
`empty_line_after_outer_attribute` produced a false positive warning when
deriving `Copy` and/or `Clone` for an item.

It looks like the second point in [this comment][that_comment] is related,
as the attribute that causes the false positive has a path of
`rustc_copy_clone_marker`.

Fixes #2475

769a1d9b6c Fix single_char_pattern for \n, \t, etc.
Single characters that are escaped weren't being searched / replaced
correctly in the hint string, so it was saying to replace, say,
`"\n"` with `"\n"` rather than `'\n'`.

3ac84b2542 Remove explicit visit_qpath method
Instead of replacing the default behaviour of the visit_qpath method,
I've moved the printing code to private method of PrintVisitor
(print_qpath).

8494f57c82 Fix author lint
The author lint was generating invalid code as shown on issue:
https://github.com/rust-lang-nursery/rust-clippy/issues/2442

I've changed the generated code to properly track cast
expressions.

Unfortunatelly, I've had to rewrite the `visit_decl` method, to
avoid that last if of the chain will be added. After looking at the code,
this last line was being added because of the `let x: char` part, but not
because of the `0x45df as char` expression.

It seems that let statements should not generate code on the author
lint, but I'm not sure that this is true or if I'm breaking
something on other code generation parts.

Finally, I've added a test for the author lint, but I'm not sure that
this needs to be added to the testsuite.
