Content-Type handling

Hi, I'm not sure it is a bug, but we used:

git config --global format.headers "Content-Type: text/plain; charset=\"utf-8\""

and recently (perhaps an Ubuntu default setup issue) the content-type
is being automatically set, the result is that patches contain this:

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Content-Type: text/plain; charset="utf-8"

This might not be the problem, but when I apply the patch I get this:

fatal: cannot convert from UTF-8utf-8 to UTF-8

which looks like a bug. Not sure it hasn't been reported before, but I
think it should take one of the content-type specifications and not
append both. I couldn't find a place to looks for previous bug reports
to check, so forgive me if this is not the right place to report it.
