In addition each valid line is 64 characters long (except the last
one) and contains only the 64 valid binhex characters.  White space is
invalid, so you can pretty much count on headers being ignored, since
they always have a space after the colon or begin with a space
(continuation lines).

A slick method of decoding would be to ignore any lines that don't fit
these criteria.  If you get a CRC error, then display the discarded lines to
the user, so that they have a chance to figure out what the problem is.
This would allow multiple parts to be processed together.
