wine-patches archive attachments have strange mime type?

[Dan Kegel]

When I'm looking at the wine-patches archives, e.g. at
http://winehq.org/pipermail/wine-patches/2006-April/025521.html
and the patch is an attachment, the archive's link to the
attachment, e.g.
http://www.winehq.org/pipermail/wine-patches/attachments/20060408/64e34006/76c37de4da1db3f8e92003d8ff125509c04bb644.diff
can't be displayed by my copy of Firefox; it doesn't recognize
the DIFF or PATCH mime types.  I tried adding them in /etc/mime.types,
and I tried looking for a way to set them in Firefox, but no joy.
Should the server be serving these up as mime type text/plain?
