## Rewrite patterns

From:

```latex
\goodbreak
```

To:

```latex

```

## Examples

Examples show the rule in isolation, not a complete normalization profile.

### goodbreak inside polynomial

Before:

```latex
x_1+x_2\goodbreak+x_3+x_4
```

After this rule:

```latex
x_1+x_2+x_3+x_4
```

Packages: base.

Rendering verified with the declared packages.

### goodbreak before condition

Before:

```latex
S_n=a_1+\cdots+a_n\goodbreak,\ n\ge 1
```

After this rule:

```latex
S_n=a_1+\cdots+a_n,\ n\ge 1
```

Packages: base.

Rendering verified with the declared packages.
