Hi

I was expecting this library to closely mimic how fetch parses relative paths, so I'm not quite sure if this is a bug or maybe my expectation is wrong. Here's an example:

parse("", "http://foo.com/a/b/c")

Navigates up the hierarchy and produces:
"http://foo.com/a/b"

But I was expecting the path remain unchanged http://foo.com/a/b/c. Here's an example with fetch(''):

Assuming i'm already on http://foo.com/a/b/c

fetch('')

would init a request for "http://foo.com/a/b/c"

Thoughts?
