Example mail with RFC2047-encoded header that confuses messageviewer
SUMMARY
Headers can contain RFC2047-encoded (Q-encoded) fragments. I got a mail that
containts such a header that confuses messageviewer into displaying it wrong.
Namely, the Cc field is
---
Cc:
=?UTF-8?Q?comp=2Dneuro=40neuroinformatics=2Ebe_=3Ccomp=2Dneuro=40neuroinformati?=
=?UTF-8?Q?cs=2Ebe=3E=2C=2C_connectionists=40cs=2Ecmu=2Eedu_=3Cconnectionists=40cs=2Ecmu=2Eed?=
=?UTF-8?Q?u=3E=2C=2C_ml=2Dnews=40googlegroups=2Ecom_=3Cml=2Dnews=40googlegroups=2Ecom=3E=2C=2C_s?=
=?UTF-8?Q?ystems=2Dneuroscience=40googlegroups=2Ecom_=3Csystems=2Dneuroscience=40g?=
=?UTF-8?Q?ooglegroups=2Ecom=3E=2C=2C_maths=2Dneuronet=40lists=2Enottingham=2Eac=2Euk?=
<ml-n...@googlegroups.com>,
rl-l...@googlegroups.com

Everything in front of <ml-n...@googlegroups.com> is decoded as if it were the
display name for that address, namely, as the string
---
"comp-ne...@neuroinformatics.be <comp-ne...@neuroinformatics.be>,,
connectioni...@cs.cmu.edu <connectioni...@cs.cmu.edu>,,
ml-n...@googlegroups.com <ml-n...@googlegroups.com>,,
systems-neuroscie...@googlegroups.com <systems-neuroscie...@googlegroups.com>,,
maths-neuro...@lists.nottingham.ac.uk <ml-n...@googlegroups.com>"

whereas actually it should not have the quotes added. (There are issues with
this list, the double commas, but that is not the problem here, I think.)
The attached mail contains this Cc header. I've added the string above without
the quotes to the Bcc header and it seems that the double commas confuse the
header parser into displaying each address twice, so that is a second issue.
