When a span starts on a line with nothing but whitespace to the left,
and there are no other annotations in that line, simplify the visual
representation of the span.
Go from:
```rust
error[E0072]: recursive type `A` has infinite size
--> file2.rs:1:1
|
1 | struct A {
| _^ starting here...
2 | | a: A,
3 | | }
| |_^ ...ending here: recursive type has infinite size
|
```
To:
```rust
error[E0072]: recursive type `A` has infinite size
--> file2.rs:1:1
|
1 | / struct A {
2 | | a: A,
3 | | }
| |_^ recursive type has infinite size
```
Remove `starting here...`/`...ending here` labels from all multiline
diagnostics.
|
|
```rust
error[E0046]: not all trait items implemented, missing: `Item`
--> $DIR/issue-23729.rs:20:9

20 | impl Iterator for Recurrence {

21 | | //~^ ERROR E0046
22 | | //~| NOTE missing `Item` in implementation
23 | | //~| NOTE `Item` from trait: `type Item;`
... |
36 | | }
37 | | }
| |_________^ ...ending here: missing `Item` in implementation
|
= note: `Item` from trait: `type Item;`
```
instead of
```rust
error[E0046]: not all trait items implemented, missing: `Item`
--> $DIR/issue-23729.rs:20:9
|
20 | impl Iterator for Recurrence {

= note: `Item` from trait: `type Item;`

Fix multiple labels when some don't have message
The diagnostic emitter now accounts for labels with no text message, presenting the underline on its own, without drawing the line for the non existing message below it. Go from
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ----^^^^^^^----
| | |
| | `b` is a good letter
|
```
to
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ----^^^^^^^----
| |
| `b` is a good letter
```
from
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^
| | |
| |
| `a` is a good letter
```
to
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^ `a` is a good letter
```
and from
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^
| | |
| |
|
```
to
```
error: foo
--> test.rs:3:6
|
3 | a { b { c } d }
| ^^^^-------^^^^
```

Make any diagnostic line to have the correct margin to align with the
first line:
```
error: message
--> file.rs:3:20
|
3 | <CODE>
| ^^^^
|
= note: this is a multiline
note with a correct
margin
= note: this is a single line note
= help: here are some functions which might fulfill your needs:
- .len()
- .foo()
- .bar()
= suggestion: this is a multiline
suggestion with a
correct margin
```
|
|
|
|
Make the suggestion list have a correct padding:
```
error[E0308]: mismatched types
--> file.rs:3:20
|
3 | let x: usize = "";
| ^^ expected usize, found reference
|
= note: expected type `usize`
= note: found type `&'static str`
= help: here are some functions which might fulfill your needs:
- .len()
- .foo()
- .bar()
```

When dealing with multiline spans that span few lines, show the complete
span instead of restricting to the first character of the first line.
For example, instead of:
```
% ./rustc foo.rs
error[E0277]: the trait bound `{integer}: std::ops::Add<()>` is not satisfied
--> foo.rs:13:9
|
13 | foo(1 + bar(x,
| ^ trait `{integer}: std::ops::Add<()>` not satisfied
|
```
show
```
% ./rustc foo.rs
error[E0277]: the trait bound `{integer}: std::ops::Add<()>` is not satisfied
--> foo.rs:13:9
|
13 | foo(1 + bar(x,
| ________^ starting here...
14 | | y),
| |_____________^ ...ending here: trait `{integer}: std::ops::Add<()>` not satisfied
|
```
|
|
|
|
Allows replacing stderr with a buffer from the client.
Also, some refactoring around run_compiler.
