The sanitizer mangles content-type when it mangles the filename, but
since it's stream processing it can't go back and change things it's
already seen.

The .txt file on the content-type line bypassed the content-type
mangling (that particular line was clean), and I bet your mail program
helpfully fixed the .doc filename to match the content-type.

I will fix this in the rewrite.

  In 1998 more than three times as many people in the US were killed
  by incompetent physicians than were killed by handguns, yet the
  President of the A.M.A. is adopting "gun safety" as his platform.
