The environment variable $EMAIL gives a better default of user's
preferred e-mail address than the hardcoded "username@hostname",
as it is understood by many existing programs.
We still honor GIT_*_EMAIL environment variables and user.email
configuration variable give them higher precedence, so that the
user can override $EMAIL or "username@hostname", as they are
likely to be more specific to the context of working on a
particular project.
