[boost] Filtered stream-buffer, part 3

For the past few weeks, some posters were talking about streambufs that 
can decorate another stream buffer.  I wrote up a third version at 
<http://groups.yahoo.com/group/boost/files/filter_stream.hpp>.

The differences from the previous version is that is actually 
implements filtering for the main functions, the reading, un-reading, 
and writing methods.  These functions use the string and allocator 
stuff I started to put in the previous version.

BTW, the <boost/io/streambuf_wrapping.hpp> header can be found in the 
Sandbox CVS.

One flaw I see currently is that _every_ character that has ever been 
(fully) read and/or putback is saved.  How should I set up the limits?
