quoted printable Fixes #1241

[ahorek]

Works, kind of, but I don't think this is the correct fix. Probably we need a custom pack?

see #1241

direct merge of this branch in master works great!

@oniram88
thanks for testing, but this isn't safe to use in production. Even it it would probably work, it violates RFC
https://www.ietf.org/rfc/rfc2045.txt

especially this one

(Soft Line Breaks) The Quoted-Printable encoding
          REQUIRES that encoded lines be no more than 76
          characters long.  If longer lines are to be encoded
          with the Quoted-Printable encoding, "soft" line breaks
          must be used.  An equal sign as the last character on a
          encoded line indicates such a non-significant ("soft")
          line break in the encoded text.

   Thus if the "raw" form of the line is a single unencoded line that
   says:

     Now's the time for all folk to come to the aid of their country.

   This can be represented, in the Quoted-Printable encoding, as:

     Now's the time =
     for all folk to come=
      to the aid of their country.

   This provides a mechanism with which long lines are encoded in such a
   way as to be restored by the user agent.  The 76 character limit does
   not count the trailing CRLF, but counts all other characters,
   including any equal signs.

I'm looking for feedback from @jeremy or someone else who knows Quoted-Printable better than me.

If you have ideas or a different approach how to fix it, give me a comment. I may take a look at it again. But right now, I don't know how to proceed with this...

I don't think this change is 100% correct and there's no response for more than a year, closing
