When I enter an article with non-ASCII in subject to cache, \201
appears in summary buffer when I reenter the group. The reason is that
gnus-cache-possibly-enter-article uses the existing headers which may
contain mule characters. I guess this may also cause Kai's bug.

Here are two patches. The first forces
gnus-cache-possibly-enter-article to re-parse the headers. The second
does a deep clean job, removing parameter `headers' of
gnus-cache-possibly-enter-article.
