Namespace qualification is misparse at the start of a line

As part of #667 prefixing an identifier has been implemented, e.g. `t'Data.Void.Void'`. However:

```haskell
{- | Blah Blah

Blah blah
t'Data.Void.Void'
Blah blah
-}
blah :: ()
blah = ()
```

is misparsed, the `t` is output literally and the link goes to `v:` instead.

A workaround that works without having to unnaturally reword your documentation, is to add `{- -}` before the `t`.
