commit 45549e9f31e462d0d1519fd678dd782da6ed5cb9
Author: Julien Lepiller <julien@lepiller.eu>
AuthorDate: Sun Apr 18 23:56:48 2021 +0200

    Makefile: Reimplement `download-po` target.
    
    The weblate API rate limit is very close to the number of files we need
    to download.  The previous implementation did not add new translations.
    
    * Makefile.am (download-po): Update target.
    (make-download-po-rule, make-check-po-rule): Remove functions.
