pull raw text of a message by message-id

We currently have a (really handy) facility to pull a message from the
archives by message-ID, eg:

http://archives.postgresql.org/message-id/603c8f070905202040v66cd3054t434c0b73aa844c63@mail.gmail.com

Could we possibly get a similar type of link that pulls the raw
contents of the message, without any HTML markup?  This would be
useful when (for example) a message contains a patch that is included
inline rather than as an attachment, and would also be useful for
tool-building (e.g. given a message-ID, download the patch and attempt
to apply it to my local working copy).
