The sort key is a (DefId, Name), which is *not* stable between
runs, so we must re-sort when loading.

This changes libfmt_macros `CharIndices` iterator into `Peekable` so it can be used without `.clone()`.
Also changed some `loop match` and `match` to `while let` and `if let` respectively (mostly for readability).
new error style:
```

This improves the #21793/#23286 situation
There is a dead code in libsyntax/parser/parse.rs, when parsing structs.
Two functions are involved:
* [parse_item_struct](cd9c9f048f/src/libsyntax/parse/parser.rs (L4691))
* [parse_tuple_struct_body](cd9c9f048f/src/libsyntax/parse/parser.rs (L4769))
The problem is that both functions handle the case with unit structs. But because
`parse_tuple_struct_body` is called from `parse_item_struct`, it never faces
this case.
This PR removes unit struct case from `parse_tuple_struct_body` function. I tested with `make -j8 check-statge1`.

This is something that I wish I had when I started contributing to Rust (not that long ago :). I plan on writing a manual for bors and the rust testing setup too, if there isn't one already.
- Headlines begin at 1st level now like the rest of the book
- All Headlines a blank line above and below
- Fix links in this chapter's TOC

Redirect stdout on the python bogosity detector. This is printing
pwd to the terminal currently.
Reformat the bogus python/cmake messages so they format correctly.
echo does not always escape newlines (it doesn't here), and multiline
strings don't whitespace munch.

This commit does some refactoring to make almost all of the `std::rt` private.
Specifically, the following items are no longer part of its API:
* DEFAULT_ERROR_CODE
* backtrace
* unwind
* args
* at_exit
* cleanup
* heap (this is just alloc::heap)
* min_stack
* util
The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is
an entry point for the `panic!` macro via the `begin_unwind` and
`begin_unwind_fmt` reexports.
