[PATCH/RFC 1/7] i18n: mark init-db messages for translation

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

Mark the init-db messages that were added in v1.7.5-rc1~16^2 (init,
clone: support --separate-git-dir for .git file) by Nguyễn Thái Ngọc
Duy for translation.

This requires splitting up the tests that the patch added so that
certain parts of them can be skipped unless the C_LOCALE_OUTPUT
prerequisite is satisfied.
