Subject: [PATCH] build: Drop positional arguments from i18n.merge_file() calls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Meson never took positional arguments in this function, but didn’t warn
about it until Meson 0.60. Drop the unnecessary arguments to fix the
warning.
