Wrong removing multi line disabled translations

[lbfeenix]

Hi, I found one minor problem but for my usecase its not minor. If I have disabled multiline translations in .po file, so PoLoader can not load it correctly, load only first line of disabled. Will be possible fix PoLoader.php function loadString from line 26 with this or similar code?

        //Multiline
        while (substr($line, -1, 1) === '"'
            && $nextLine !== false
            && (substr(trim($nextLine), 0, 1) === '"' || substr(trim($nextLine), 0, 4) === '#~ "')
        ) {
            if (substr(trim($nextLine), 0, 1) === '"') { // Normal multiline
                $line = substr($line, 0, -1).substr(trim($nextLine), 1);
            }
            if (substr(trim($nextLine), 0, 4) === '#~ "') { // Disabled multiline
                $line = substr($line, 0, -1).substr(trim($nextLine), 4);
            }
            $nextLine = next($lines);
        }

Hi, thank you for warning about this. Do you want to work on a PR including test reproducing this error?

Hi, although I'm not new to using git or writing code, I'm using github for the first time, so I try create PR with some comment (I hope it have sense), but do not know how create some test here, or what type of test do you mean.
