We discussed this a bit last year, but didn't come to any conclusion,
but I think on the whole, having base64-decode be strict or non-strict
here doesn't make much practical difference (because it's very uncommon
to strip the trailing = padding characters), but theoretical paranoia
about this somehow leading to subsequent errors...  somehow...  may be
warranted.

So I'm closing this bug report.
