Previously we only show at most 6 lines of suggestions and, if the
suggestions are more than 6 lines apart, we've just showed ... at the
end. This is probably fine, but quite confusing in my opinion.
This commit is an attempt to show ... in places where there is nothing
to suggest instead, for example:
Before:
```text
help: consider enclosing expression in a block
|
3 ~ 'l: { match () { () => break 'l,
4 |
5 |
6 |
7 |
8 |
...
```
After:
```text
help: consider enclosing expression in a block
|
3 ~ 'l: { match () { () => break 'l,
4 |
...
31|
32~ } };
|
```
