The way we do it currently is by hooking into public-inbox where the 
email subject is in the commit log. So for us to grab all new subjects 
it's a single git call, whereas getting the message body requires a git 
call per message. This is why we pre-filter by subject, as it's a cheap 
way to avoid needing to issue hundreds of git calls looking for possible 
matches in message bodies.

Would you consider recording the message-id of the pull request as part 
of the commit message? This would be a sure way for us to be able to 
catch all possible cases. In fact, this would allow me to throw out most 
of the bot logic, as it would become unnecessary. E.g. the merge commit 
would look like:

Merge tag 'foo' of git://git.kernel.org/bar

Pull foo features

* foo
* bar
* baz

However, I suspect that getting message-ids for all your pull requests 
would significantly complicate your workflow.
