15+ years is the best argument for a rewrite. Wget's basic functionality is 
quite simple.
But you're right: it took 15+ year to add some add-ons and tweak for all the 
little corner cases.

And I am absolutely on your's and Micah's side regarding the test cases.

It would be perfect, to have a large test suite. If someone works out a test 
suite design for wget1, I would spend some time into the coding.
Once finished, the test suite should be good for the wget2 thing...

Any volunteers to create a draft for a test suite design ?
I know there is a test suite, but how usable is it, what is missing, what is 
needed ? Could anyone give us an overview ?
