I am not native but I have a slight worry that a template that lists
only core.{user,email} and marked as Git's "user configuration" will
easily mislead the reader that the file is only about these two
(i.e. I am telling the stupid Git who I am), and is not meant to
hold any other configuration that are private to the user. I still
have funny feeling about "user-wide", but "Git's user configuration"
somehow smells worse for that reason.
What the patch attempts to do is a good idea and the code looks done
right. Let's queue it and hope people can polish the wording.
Thanks.
