    Normally upon trying to open a large file, we get a warning like "file

    compressed, won't cause the warning upon attempts to open/view it.

That is because Emacs has no way of telling how big it is
until after uncompressing it.

That's not really true: GNU zip has the --list option, which generates
output like:

compressed  uncompr. ratio uncompressed_name
 12574759  58689536  78.5% foo.txt
