True enough, and in that case, the try-to-fix-broken-base64 function just
returns the input text.  No harm, no foul.  The performance penalty should
be reasonable.  One split() and length check for each part in the common
case.  The try-to-fix function is only called if it's long enough, which
should be rare.
