In peg email_storage--marc it is defined that the content-type 
of header blocks is message/rfc822 and of body blocks is 
the content-type specified in the email's header.
The problem is that PermanentTextScroll only accepts 
"text/plain; charset=UTF-8" and "application/x-gzigzag-GZZ1".
Since we want to transclude from both header and body, 
PermanentTextScroll should also accept the content-type
"message/rfc822" and "text/plain" in other charsets than UTF-8.

Changes
-------

PermanentTextScroll has to be changed accordingly. There it
will be necessary to determine the charset used in the body
to set the appropriate charset for the String defined in
load().
