euank 234a7c19a4 Default values for both user.name and user.email
The previous behavior was to set default values only if user.name was
not set, but to always set it for both. This only sets a value if there
wasn't one; this fixes cases where someone has a user.name but no
user.email (see included Dockerfile) or someone has a user.email but no
user.name (before the email would have been over-written).
