> It is possible to skip "RE:" without encoding the string again. It needs to
> decode MIME encode but without charset conversion then we can search for "RE:",
> remember the positions and copy the rest of the string over. This way, the
> result is always shorter than the original and no modification to the subject
> except for removing "RE:". Probably, we want that functionality in the MIME
> decoder/encoder interface. I think this would be not a small change, so not for
> moz1.0.
