- I tried to do this once because binary images would inevitably have a
- ctrl-d in them. Stripping them out doesn't work, nor does converting
- them. And on the mac, there's no reliable, simple way to tell if the
- ctrl-d is part of a binary image. But if the ctrl-d's are in a certain
- place (before %%BeginDocument or after %%EOF) then they're probably safe
- to strip.
