[Bug-wget] [Bug-Wget][PATH} Cleanup the test suite and add documentation

[Darshit Shah]

Hi,

I've spent some time cleaning up the test suite and adding some extra
documentation so that it is easier for others to add new tests.
Attaching a patch which adds docstrings and fixes quite a few
indentation issues in the test suite code. I'll probably take some
time out and add new tests soon.
