Wait. I don't understand something. If it doesn't use the -n flag, how  
can we produce an md5sum-identical patched file? (The mtime is  
unpredictable.) This poses an extra problem, or not? I just did an  
effective test on xdelta3-diffing .tar.gz files and I saw that the  
patched md5sum indeed differ from the original one :-( Maybe we should  
search for a gzip header manipulation tool...

Bye
