Or is it "encoding"?  Gah, Perl character set handling
confuses me no matter how many times I RTFM :<

This contains placeholders for attachment downloading
which will be in a future commit.

Unlike Email::MIME::walk_parts, this is non-recursive and gives
depth + index offset information about the part for creating
links for later retrieval

It is intended for read-only access and changes are not
propagated to the parent; however future versions of it
may clobber bodies or the original version as it iterates
to reduce memory overhead.

It is intended for making it easy to locate attachments within a
message in the WWW view.

msg_iter lets us know the index of the attachment,
allow us to make more sensible labels and in a future
commit, hyperlinks to download attachments.

This can be useful for lists where the convention is to
attach (rather than inline) patches into the message body.

Email::MIME >= 1.923 and < 1.935 would drop too many newlines
in attachments.  This would lead to ugly text files without
a proper trailing newline if using quoted-printable, 7bit, or
8bit.  Attachments encoded with base64 were not affected.

These versions of Email::MIME are widely available in Debian 8
(Jessie) and even Ubuntu LTS distros so we will need to support
this workaround for a while.

Having a file start with '.' or '-' can be confusing
and for users, so do not allow it.
