There is in fact a message about the xlog location (unless you switch off wal entirely), but having another one right before that mentioning the completed checkpoint sounds ok to me. There's also some inconsistencies around which messages are prepended with "pg_basebackup: " and which are translatable; I guess all messages printed on --verbose should be translatable? Also, as almost all messages have a "pg_basebackup: " prefix, I've added it to the rest.
