In the HTML+ spec I introduced a SIZE attribute for anchors with
this in mind. People persuaded me to take it out, but maybe we
should put it back again :-)

Yup. I see two scenarios:

(A) Browser builds directory listing for FTP host/path.
The size is stuck into each <A> element for use when
the user clicks on a file

(B) HTTP server builds directory listing on behalf of client
The size is stuck into each <A> element for use when
the user clicks on a file

In each case the information is fresh and so valuable for displaying
a progress gauge.

Thanks for bringing this up - I will write it up in the next version
of the HTML+ spec.
