mm-bidy-7-or-8 seems bogus to me [pgnus 0.95]

[Soren Dayton]

Consider a body that is nothing but nulls.  This body is not
encoded. (see the skip-chars-forward below)  (note that
mm-find-charset-region has a similar test in it)  

It seems to me that it ought to be encoded 

Concretely it means that tar files don't get encoded.  And that people 
on the other side can't read them.  MIME is supposed to fix this
problem. 



Perhaps this should be "\001-\177" or even something like
"\027-\177".  What do people think?

Thanks
Soren

I think the latter is not a very good idea - I'd go more for something
more, like "\011\012\015\027-\177" to allow TAB, LF, and CR in ASCII.
\014 (FF) is probably okay, too.  Some other characters require
thought (ESC?).

Fair enough.  You get my point. pgnus does the wrong thing.
