Comment (by catalyst):

 I'm sorry, after I looked at the patch while more awake I realized that
 the NULs were to overwrite the `=` padding.  `base64_encode_nopad()` seems
 like it would be a better option, though.  I think it's kind of inelegant
 at the moment and requires that the destination buffer be large enough to
 hold the padded (and NUL-terminated) encoding, but using it here would
 eliminate some code duplication.
