Correct format for patch attachments

PLEASE PLEASE PLEASE make sure that, whenever you send a patch as an attachment, the type of the patch is "text/plain". I have seen patches in "application/octet-stream", "application/x-patch", "application/x-diff", "text/x-patch", etc. etc. These weird MIME types screw up my mail reader (and I imagine many other people's, too), so that I have to save the patch out to another directory, go find it again, and open it up in some random Windows text editor crap. If the type is "text/plain", it comes up nicely right in my mail reader, and makes it much more likely that I will carefully go over the patch. So can we agree upon a standard, i.e. all patch attachments are MIME type "text/plain"? Thank you. Ben
