Followup, second try.
First of all, I'd like to apologize to the list for my previous message, I
borked some finger gymnastics when switching tabs and sent and incomplete
one. My fault. Sorry.
Now what I tried to say was:
I did not spot it at first, looking at
http://www.gzip.org/zlib/rfc-gzip.html#file-format I see:
ISIZE (Input SIZE) This contains the size of the original (uncompressed)
input data modulo 2^32. And given gzip -l is usually much faster than -tv I
suspect it's just reporting this size.
