Spaces issues

### Description of the modifications

Some spaces are not correctly handled. Most of the time, it happens with the following configuration:

original documentation:
```
The original text has intended
break-lines.
```

converted documentation:
```
The original text has intendedbreak-lines
```

A space should be added between ``intended`` and ``break-lines`` but it's not correctly taken into account when resizing the paragraph.

### Useful links and references

Start by reproducing the documented conversion example and read the linked gline and dist discussions for the relevant context. Done means the converted paragraph preserves a space between “intended” and “break-lines” when the paragraph is resized.
