Leah Neukirchen b962fb6be0 rfc2047: skip whitespace everywhere during base64 decoding
> The encoded output stream must be represented in lines of no more
> than 76 characters each.  All line breaks or other characters not
> found in Table 1 must be ignored by decoding software.  In base64
> data, characters other than those in Table 1, line breaks, and other
> white space probably indicate a transmission error, about which a
> warning message or even a message rejection might be appropriate
> under some circumstances.
