magnum 2113b3bb7d Avoid false positives in pkzip formats 
After inflating data decrypted with an incorrect guess, you may get
Z_STREAM_END (weakly indicating a correct guess) although the output length
doesn't match the expected.  If the CRC-32 randomly match as well, we had
a false positive before these tests were added.  Crazy yes, but I did
see it happen!
