[twill] Bug in FakeResponse

[Titus Brown]

-> I'm trying to use twill to examine forms in webpages and it fails all the 
-> time. I have after a fairly long debugging session pinpointed the problem.

Jacob, thanks for tracking this down.  Is there any way you can send me
something to reproduce your original problem?

(I'm interested in adding your bug into some tests, so that I can avoid
regressions!)

cheers,
