[Haddock] Qualification of non-hyperlinked identifiers

[David Waern]

Hi Tobias,

I was reading the code for the 'ppDocName' function and noticed that
you don't apply your qualification logic to 'Undocumented' names. Is
there a reason for this? Undocumented names are just names that
Haddock didn't find in the .haddock files it searches and thus won't
generate a hyperlink for. They are still shown however and I guess it
would be more consistent to qualify them as well?
