RMAIL, MIME clean-up, ignoring headers

[Alexander Pohoyda <alexander.pohoyda@gmx.net>]

Hello everybody,

I have developed a set of functions to recursively parse a
MIME-compliant message and to handle separate entities in it.

Now, I would like to hide some header fields not only in the
top-level entity (message), but also in it's sub-entities (if
any). The problem I see is that the function rmail-clear-headers
*deletes* ignored header fields.
In case of a simple message this is not a problem, because the
original message header is stored elsewhere. However, we'd better not
delete headers from MIME-entities, and I don't see a clean way how we
should store original entity headers outside of the visible message
itself.

Thus, my question: is it a good idea to change the code not to delete
headers, but to make them invisible instead? This would also make
rmail-toggle-headers function *much* simplier!

Thank you for any response.
