Keep footnote backlinks with text

Browse source 
This inserts a non-breaking space before backlinks to prevent them from being separated from footnote text.

Results in the following when text wraps:

```
1. Roses are red, violets are
blue ↩
```

Instead of this:

```
1. Roses are red, violets are blue
↩
```
