MIME headers in introductory message (git send-email --compose)

Add MIME-Version/Content-Type/Content-Transfer-Encoding headers in
messages generated with git-format-patch. Without it, messages
generated without using --attach or --inline didn't have any
content type information.

Isn't that job for send-email (or user's MUA)?  I really do not think
we want to clutter format-patch output any more than necessary.

By the way, 'git send-email --compose' does not add MIME headers to 
introductory message. All non-Ascii chars will output something 
undefined in receivers' end.

I guess the right way would be to detect user's charset (locale) and add 
appropriate MIME headers. Also, the Subject field should be encoded if 
it contains non-Ascii characters.
