Long inline links reflowing is problematic

If an inline link is too long, it might get reflowed in a suboptimal way. It happens when you have a line that looks like:
```markdown
Some text with [a link](https://example.org/some-very-looooooooooooooooooooooooooooooooooooooooooooooooooong-link.html)
```
This gets reflowed like so:
```markdown
Some text with [a link](
https://example.org/some-very-looooooooooooooooooooooooooooooooooooooooooooooooooong-link.html)
```
Some Markdown converters (like libtext-markdown-perl) don't like this, and will generate this HTML:
```html

Some text with [a link](
https://example.org/some-very-looooooooooooooooooooooooooooooooooooooooooooooooooong-link.html)

```
I think the way it is reflowed is valid CommonMark, but it would be nicer for some tools, and arguably as well for a human reader, if the above example would be reflowed as:
```markdown
Some text with
[a link](https://example.org/some-very-looooooooooooooooooooooooooooooooooooooooooooooooooong-link.html)
```
