Here are some interesting statistics, though, about the per-line
annotations.
For this file:
http://goffredo-baroncelli.homelinux.net/bazaar/hgweb_devel?cmd=content;rev=ghigo@therra.bhome-20060104222604-bb16793970cb0fbe;pathrevid=ghigo@therra.bhome-20060104230125-d355a583982aee0a;path=webserve/README.txt

The raw README.txt is 11925 bytes.
The html is 172855 bytes. (Yes 172kb)
If all I do is change:
<a aoeuaoeu>55</a>:<a aoeuaoeu>ghigo@</a>
to
<a aoeuaoeu>55:ghigo@</a>

It drops to 1009943 bytes.
That is cutting it almost in half. Without doing any compression. Though
I agree, adding compression should help a lot, since each line is
frequently the same content as the previous one.

After gzip, I have:
8343 hgweb_devel.html.gz
7315 test.html.gz

So down from 170k to 7-8k. It would definitely be worth implementing. I
think Goffredo would appreciate a 24x decrease in bandwidth consumption.
