      * IO::Uncompress::Base.pm
        - Fixed problem with LimitOutput where a call to uncompress
          created more uncompressed output, but didn't consume any of
          the input buffer. The symptom is the underlying compression
          library (zlib or bzip2) thinks the input stream is corrupt.
