Remove the name "multi-line string literal" since the rule appears to affect each line-break individually rather than the whole string literal. Re-word, and remove the stray reference to raw strings.

A user in IRC was having trouble because they used `main.rs` when they were trying
to migrate a library. The `[[lib]]` key is not easily found, and the `main.rs`/`lib.rs`
distinction doesn't seem to exist in trpl

Improve example for as_string and add example for as_vec

Provide a better example of `as_string` / `DerefString`'s unique capabilities.
Use an example where (for an unspecified reason) you need a &String, and
show how `as_string` solves the problem without needing an allocation.

08c0299a82 Rollup merge of #24797 - roryokane:patch-1, r=nikomatsakis
The minus sign ‘−’ is the same width as the plus sign ‘+’, so the button’s transition between the two symbols will look slightly smoother.

If you don’t want to use literal Unicode characters, I can change ‘−’ to `\u2212`. I’m not starting with that suggestion because ‘−’ is easier to read and understand, and if I used `\u2212`, it would probably be necessary to also comment the usage on each line to explain what character is being used.

805349a50b Bug fix: Rvalue(ByRef) will issue a lifetime_end as its post_store, which is wrong.
Kudos to dotdash for tracking down this fix.

Presumably the use of `ByRef` was because this value is a reference to
the drop-flag; but an Lvalue will serve just as well for that. dotdash
argues:

> since the drop_flag is in its "final home", Lvalue seems to be the
> correct choice.

24f213d023 drive-by fix: scheduled drops are executed in reverse order.
That is, scheduled drops are executed in reverse order, so for
correctness, we *schedule* the lifetime end before we schedule the
drop, so that when they are executed, the drop will be executed
*before* the lifetime end.

5c60145323 Auto merge of #24820 - bradking:fix-windows-process-spawn-command-line, r=alexcrichton
Fix `make_command_line` for the case of backslashes at the end of an
argument requiring quotes.  We must encode the command and arguments
such that `CommandLineToArgvW` recovers them in the spawned process.
Simplify the logic by using a running count of backslashes as they
are encountered instead of looking ahead for quotes following them.

Extend `test_make_command_line` to additionally cover:

* a leading quote in an argument that requires quotes,
* a backslash before a quote in an argument that requires quotes,
* a backslash at the end of an argument that requires quotes, and
* a backslash at the end of an argument that does not require quotes.

72e8f7b1ab Change literal minus ‘−’ to HTML entity ‘−’
So that if people accidentally delete the character, they won’t re-type it as a hyphen, which would cause bugs.

I changed ‘+’ too, even though it won’t be re-typed incorrectly, so that it is easier to see when plus is used as a symbol for the button, and when it is used as an operator in code. It also makes it clearer that the use of an entity for minus is on purpose, so people won’t be tempted to replace the entity incorrectly with a hyphen character.

5e37729036 Add a new test group, rfail-full that runs rfail tests with fulldeps.
In most places in mk/tests.mk, it's positioned after rpass-full and
before cfail-full (because rfail comes before cfail). The order of tests
seems a little inconsistent, but reordering everywhere would obscure this
commit.

6365080c5c Auto merge of #23085 - goffrie:interpolating-quote, r=huonw
This changes the `ToTokens` implementations for expressions, statements, etc. with almost-trivial ones that produce `Interpolated(*Nt(...))` pseudo-tokens. In this way, quasiquote now works the same way as macros do: already-parsed AST fragments are used as-is, not reparsed.

The `ToSource` trait is removed. Quasiquote no longer involves pretty-printing at all, which removes the need for the `encode_with_hygiene` hack. All associated machinery is removed.

New `Nonterminal`s are added: NtArm, NtImplItem, and NtTraitItem. These are just for quasiquote, not macros.

`ToTokens` is no longer implemented for `Arg` (although this could be added again) and `Generics` (which I don't think makes sense).

This breaks any compiler extensions that relied on the ability of `ToTokens` to turn AST fragments back into inspectable token trees. For this reason, this closes #16987.

As such, this is a [breaking-change].

An actual typeck error is the cause of many failed compilations but an
unrelated bug is being reported instead. It is triggered because a typeck
error is presumably not yet identified during compiler execution, which
would normally bypass an invariant in the presence of other errors. In
this particular situation, we delay the reporting of the bug until
abort_if_errors().

Closes #23827, closes #24356, closes #23041, closes #22897, closes #23966,
closes #24013, and closes #23729

**There is at least one situation where this bug may still be genuinely
triggered (#23437).**

These new intrinsics are comparable to `atomic_signal_fence` in C++,
ensuring the compiler will not reorder memory accesses across the
barrier, nor will it emit any machine instructions for it.
