They do work, but two istream iterators using the same stream will compare as 
equal if either 

- neither are end-of-stream markers (ie both are still valid to read) or
- both are end-of-stream markers (ie neither are still valid to read).

In other words, they do not compare on the position within the stream.  Not 
all input streams will have meaningful positions (file streams will, others 
generally won't).
