Yeah, I didn't expect to see so much churn, especially out of the
fuzzers, but especially the msoffice binary filters tend to do a lot of
reads before an eventual check of the stream to see if eof was hit, or
otherwise expect to be able to keep going. ppt/escher filters seems to
be particularly full of it, so in the end I think reverting is safer
than not.
