5291,bzip2_decompressor does not work properly with a filtering_streambuf,Chris Steenwyk <chris.steenwyk@…>,Jonathan Turkanis,"The revision 63057 of boost/iostreams/filter/bzip2.hpp seems to have broken the ability to use the bzip2 decompressor in a filtering streambuf.  When I pass a stream into the buffer it throws data_error_magic. Stepping through the code I can see it correctly decode the zipped data, but then it continues to attempt to decode data even after eof is reached.  

Looking at the changes to bzip2_decompressor_impl I see the following issues:
1.) The function returns true even if _eof is set to true.  This causes the ""done"" flag in the ""Read"" function in symmetric.hpp to be set to false, which causes the bzip2_decompressor_impl function to execute again, after EOL.
2.) On the second execution when _eof is set, the ""close"" function resets _eof to  false, which can cause the function to throw the exception.

In the specific instance I am using, my bzip compressed section is embedded in the middle of the stream, so src_begin won't equal src_end.",Bugs,new,To Be Determined,iostreams,Boost 1.45.0,Problem,,,
