No problem. One might add these test cases to the test script uploaded to check for this case.

'Line nr 3ab Line nr 2a Line nr 1 :TGluZSBuciAzYWIg TGluZSBuciAyYSA= TGluZSBuciAxIA==',
'Line nr 3ab Line nr 3ab Line nr 1 :TGluZSBuciAzYWIg TGluZSBuciAzYWIg TGluZSBuciAxIA==',

What if the first block isn't padded with '=' because the data it's encoding is
a multiple of three bytes in length?

$s1 = base64_encode("Line nr 1 bcdefgh\n");
$s2 = base64_encode("Line nr 2 \n");
$str = $s1."\n".$s2;
echo $str;
echo base64_decode($str);

I just uploaded a patch as well as a test script (for 8.0.3)
There should be no change in the old behaviour for single base64 blocks.

I may agree, but I am relating to a world outside my control, not an ideal world.
