A looooooong time ago, I suggested:
<A HREF="ftp://host/file.tar.Z" CONTENT-TYPE="application/x-tarZ">
a tar file</a>
which would be enough information for the browser to decide that
the tar file is not something it can display in the reading window.
The concept was introduced in the MIME RFC. I thought we should
use it. I got vetoed, cuz timbl (and others) thought such things belong in
the protol. But this rules out FTP as a protocol. But wait! we
do use FTP protocol. So we end up with the current broken situation.
I still think I was right ;-)
