By default, an StGit patch separates the subject from the commit message
and headers as follows:
$subject
From: $author_name <$author_email>
$message
---
$diffstats
We test git-am's ability to detect such a patch as an StGit patch, and
its ability to be able to extract the commit author, date and message
from such a patch.
