Hi,

I was wondering how the -p1 (download only HTML files) option works, in
particular how and when the decision is made whether to add a URL to the
download queue. 

Is is possible to mimic the behaviour to get the same nice detection of HTML
but also include e.g. pdfs? To allow pdfs using

  +prefix/*.pdf

I would need to first specify an exclusion such as 

  -*

which means that I also need to specifically include all html files again
which -p1 achieved more reliably.

cheers,
Christian
