[PATCH 02/13] init: split out template population from create_default_files()

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

The create_default_files() function only has one caller,
init_db(). Let's have it call a separate create_template_files()
function.

This refactoring changes nothing about how the repository is
initialized, but makes subsequent changes to create_template_files()
easier to read, e.g. because new variables we'll need will be scoped
to that function.
