bug#10536: 23.3; Make base64-decode more fault tolerant |

Hello,
Not a bug in Emacs, but I have received base64-encoded mails from a
not-so-small company which could not be decoded. It turns out that
there was a missing padding character, i.e. the last quartet was
"xy=" rather than the proper "xy==".
I would suggest that base64-decode should tolerate this, like with
the appended patch.
Regards,
Wolfram.
