[dev] MIME.php wrapHeaders corrupting filenames

I've just started to take a look at this, but a quick comment on this 
solution.
Although this is the correct way to break these lines according to RFC 2231,
there is a *boatload* of mailers that don't support this.  So implementing it
this way is out of the question, at least for right now (IMP, for example,
supports decoding RFC 2231 encoded strings, but we have to do it in an
extremely hackish way as c-client/PHP doesn't even support this format).

Now that I have been thinking about this for a few minutes... isn't this the
same problem and/or potential solution I discussed here:
http://marc.theaimsgroup.com/?l=horde-dev&m=108334367512331&w=2

If this solution doesn't work, most likely we will have to just have 
the line be
longer than 78 characters since that is the only way I can see right now that
would work with most/all mailers.
