} The code for writing crossposts makes no distinction between one

} trying first to create some hard- and then softlink between the
} destination files and at last, if both fails (because the destination
} file already exists), writes the first archive over the second.
} 
} 
} I appended a patch that corrects this behavior.

Just committed.  Thank you.
