.. nonce: 8rwPxe
.. section: Security

Fix bug in the folding of rfc2047 encoded-words when flattening an email
message using a modern email policy. Previously when an encoded-word was too
long for a line, it would be decoded, split across lines, and re-encoded.
But commas and other special characters in the original text could be left
unencoded and unquoted. This could theoretically be used to spoof header
lines using a carefully constructed encoded-word if the resulting rendered
email was transmitted or re-parsed.

``from __future__ import barry_as_FLUFL`` now works in more contexts,
including when it is used in files, with the ``-c`` flag, and in the REPL
when there are multiple statements on the same line. Previously, it worked
only on subsequent lines in the REPL, and when the appropriate flags were
passed directly to :func:`compile`. Patch by Pablo Galindo.
