Title: Fix prufer docstrings so that documentation is buildable again.

Docs don't build in master because See Also sections use wrong syntax,

```
See Also
========
:class: 'Prufer', :function:'to_prufer()'
```

Because we use numpydoc extension, `:class:` and `:function:` are not needed And even if they were, the syntax is still wrong - note the whitespace after `:class:` and ' instead of `.

`make html` produces ValueError in master, `ValueError: :class: 'Prufer' is not a item name`.

Bug was introduced in PR 876.
