Description:
------------
RFC 2045 says:
"All line breaks or other characters not found in Table 1 must be ignored by decoding software."

However if a caracter such as a space is in the encoded data (which some encoders such as newegg.com do) then the base64_decode does not work.

Reproduce code:
---------------

or
http://www.worldlinked.net/blog/files/testbase64.phps


Expected result:
----------------
Hello, There seems to be a problem with php's base64_decode() function. Whitespace needs to be trimmed from the email before it will properly decode.

Actual result:
--------------

This bug was first reported in

however the patch listed there was either never applied or does not work.

Hmm, Im pretty sure it still fails.  We tried it also with 4.4.0. I did notice though that if you cut and paste the phps file that the spaces do not appear in $enctext in the first line.  Perhaps you can try again and manually put spaces at the beginning of each line, or you can download a tgz of the php file here:
