I think the web server may be misconfigured and giving out incorrect

    $ foo() { env -u http_proxy curl -sSI "$@" | egrep -i '^content-'; }
    $ foo http://www.mirrorservice.org/sites/ftp.gnu.org/gnu/bc/bc-1.06.tar.gz
    Content-Length: 278926
    Content-Type: application/x-gzip
    $ foo http://www.marutan.net/rpcemuspoon/086/rpcemu-0.8.6.tar.gz
    Content-Length: 306784
    Content-Type: application/x-gzip
    Content-Encoding: x-gzip

FSF's headers are saying the file is of type gzip, the length of the
(gzip'd) file is 278926 , and here it is...

marutan.net is saying the file is of type gzip, we're shipping it to you
encoded with gzip, and that the encoded length is 306784.  IOW, marutan
is saying it's gzip-ing a gzip'ed file before sending it to me.  The
user agent is reversing the temporary, for shipping only, gzip encoding
and intends to leave the user with the original gzip'd file.  But
because marutan didn't double-gzip it, it only claimed to, the user is
left with a non-gzip'd file.

That some UAs correctly gunzip and others don't is a seperate issue.
