The unzip command did not provide a way for the caller to get any information about the uncompressed size. To make it better usable in scripts, we now store the uncompressed size in the `filesize' variable, like we do when for example loading a file over the network or when reading it from a file system. Following that analogy, it is only consequent to also print the size.
