- update to 1.9:
* main.cc (main): Report an error if a file name is empty.
Make '-o' behave like '-c', but writing to file instead of stdout.
Make '-c' and '-o' check whether the output is a terminal only once.
Do not open output if input is a terminal.
* main.cc: New option '--check-lib'.
* Replace 'decompressed', 'compressed' with 'out', 'in' in output.
* decompress.cc, dec_stream.cc, dec_stdout.cc:
Continue testing if any input file fails the test.
Show the largest dictionary size in a multimember file.
* main.cc: Show final diagnostic when testing multiple files.
* decompress.cc, dec_stream.cc [LZ_API_VERSION >= 1012]: Avoid
copying decompressed data when testing with lzlib 1.12 or newer.
* compress.cc, dec_stream.cc: Start only the worker threads required.
* dec_stream.cc: Splitter stops reading when trailing data is found.
Don't include trailing data in the compressed size shown.
Use plain comparison instead of Boyer-Moore to search for headers.
* lzip_index.cc: Improve messages for corruption in last header.
* decompress.cc: Shorten messages 'Data error' and 'Unexpected EOF'.
* main.cc: Set a valid invocation_name even if argc == 0.
