Outside of the git commit text, no, we are not going to be adding
anything additional to the report, UNLESS someone wants to add
additional text to it, and then we will be glad to update a CVE entry
with the additional information.

Here's an example of what the CVE announcement is going to look like for
a "test" that we have been doing for our scripts

Note, I am NOT saying this is a valid CVE-like commit, I only chose it
because it is a type of entry that our tools need to handle properly
(one where the fix was for a commit that was only in a stable tree, and
mainline never saw the problem.)  There are many different "styles" of
fixes that we need to handle when it comes to version information.

It will also be in JSON format on the cve.org site if you wish to parse
it automatically with tools.  We are still working out the proper format
of the JSON entries of the version information and should hopefully have
an agreement of how to do this early next week, as the logic there isn't
exactly "simple".

If the announcement format needs additional work, please let us know.
