d660739f9a Rollup merge of - huonw:unstable-words, r=aturon
It is not totally clear if we should just use whitespace, or if the full
unicode word-breaking algorithm is more correct. If there is demand we
can reconsider this decision (and consider the precise algorithm to use
in detail).

Implement rules described in .

Fixes https://github.com/rust-lang/rust/issues/22211.

~~Based atop PR https://github.com/rust-lang/rust/pull/22182, so the first few commits (up to and including "Pacify the mercilous nrc") have already been reviewed.~~

e4e7aa2856 Auto merge of - eddyb:rvalue-promotion, r=nikomatsakis
This includes everything necessary for promoting borrows of constant rvalues to `'static`.
That is, `&expr` will have the type `&'static T` if `const T: &'static T = &expr;` is valid.
There is a small exception, dereferences of raw pointers, as they misbehave.
They still "work" in constants as I didn't want to break legitimate uses (are there any?).

The qualification done here can be expanded to allow simple CTFE via `const fn`.

f58a1bfa98 Fix fallout in libsyntax from RFC 599. Clarity and efficiency seems to be mostly improved, to my eye.
Nonetheless, as this commit demonstrates, the previous commits was a [breaking-change].

In practice, breakage is focused on functions of this form:

```rust
fn foo(..., object: Box<FnMut()>)
````

where `FnMut()` could be any trait object type. The older scheme defaulted objects in argument
position so that they were bounded by a fresh lifetime:

```rust
fn foo<'a>(..., object: Box<FnMut()+'a>)
```

This meant that the object could contain borrowed data. The newer
scheme defaults to a lifetime bound of `'static`:

```rust
fn foo(..., object: Box<FnMut()+'static>)
```

This means that the object cannot contain borrowed data. In some cases, the best fix
is to stop using `Box`:

```rust
fn foo(..., object: &mut FnMut())
```

but another option is to write an explicit annotation for the `'a`
lifetime that used to be implicit.  Both fixes are demonstrated in
this commit.

97503e1c1e Rollup merge of - brson:installer-next, r=alexcrichton
Highlights:

* Adds an 'uninstall.sh' script to `/usr/local/lib/rustlib/uninstall.sh`, the path to which is printed during installation.
* Components can be deselected during install, like `install.sh --without=rust-docs`.
* Components can be listed with `install.sh --list-components`.
* Vastly reduces spew during install (but supporting a `--verbose` option).

Typicall install run looks like:

```
brian@brianX1:~/dev/multirust⟫ sudo ./install.sh
[sudo] password for brian:
install: creating uninstall script at /usr/local/lib/rustlib/uninstall.sh
install: installing component 'rustc'
install: installing component 'cargo'
install: installing component 'rust-docs'

    Rust is ready to roll.
```

Needs to be merged right before corresponding PRs to cargo and rust-packaging.

16b24f15bd Rollup merge of - kmcallister:pub-macro, r=nick29581
It's not clear what this means, because a macro in item position can expand to zero or more items.  For now we disallow it, which is technically a

    [breaking-change]

but is landing without an RFC.  The `pub` keyword previously had no effect, which seems quite unintended.

`PathBuf` does implement `Hash`, but `Path` doesn't. This makes it
annoying if you have a `HashMap` with `PathBuf`s as keys, because
it means you have to convert a `Path` into a `PathBuf` and get a
reference to it simply to perform operations on the `HashMap`!

1b86ebe257 Rollup merge of - bluss:range-64-is-not-exact-size, r=alexcrichton
Fixes 

`Range<u64>` and `Range<i64>` may be longer than usize::MAX on 32-bit
platforms, and thus they cannot fulfill the protocol for
ExactSizeIterator. We don't want a nonobvious platform dependency in
basic iterator traits, so the trait impl is removed.

The logic of this change assumes that usize is at least 32-bit.

This is technically a breaking change; note that `Range<usize>` and
`Range<isize>` are always ExactSizeIterators.
