I'm looking at:
	https://xenbits.xen.org/xsa/advisory-391.html
and I don't see a git id anywhere, where do you see the v3 announcement
saying that?

Also, the json file at:
	https://www.cve.org/CVERecord?id=CVE-2021-28711
points to:
	https://xenbits.xenproject.org/xsa/advisory-391.txt
Not to the html document, which is correct?

But to be fair, I'm not going to be able to search all links in all json
files for all entries, so even if the 391 announcement did show the git
ids for the changes, I would miss it.  All I can do is search the json
repo for all CVEs.

thanks,
