[PULL] Collected patches

[John Keeping]

Hi Jason,

My changes are a collection of bugfixes, including a series fixing an
URL-parsing issue I found by running AFL.

I've picked up Roy's patch as well because I think it's in decent shape
and it makes it easier to write Python filters that do the right thing
with non-ASCII content.
