use HG10UN header for uncompressed bundle - use HG10UN instead of HG11 for uncompressed bundles header - check HG10BZ for compressed bundle - better error handling for invalid header some notes: - people who created uncompressed bundle will no longer be able to use them (it could be fixed with hand-editing) - older hg cannot detect an uncompressed bundle (bzip2 decompression will fail).
