Filter script to remove html, fullquotes and header lines

[Martin Trautmann]

Hi all,

do you know about any mutt script that would go from message to message and

1) remove a html part if a plain text part is given

2) remove all trailing lines,
    starting with a quote sign ">"
    and at least e.g. 10 occurences

   such as (^>[.*][\r\n]){9,} before the end of the message

   Maybe I could append xzxzxzx to the end of the message first, delete 
a fullquote up to there and remove xzxzxzx again?

   Bonus: Do not remove fullquotes for messages without in-reply-to or 
references headers.

3) remove header lines which are longer than 5 lines

I want to shrink the size of some mailboxes for archive purposes, 
without throwing away too much.

Thanks,
Martin
