Note that the relative time output is translated, see all the Q_()
calls in show_date_relative().  Consequently, these tests fail in
GETTEXT_POISON builds.  Please use 'test_i18ncmp' instead.

Furthermore, I think it would help readibility of this helper function
if the commands in the 'test_expect_success' block were indented.
