Merge branch 'eb/format-patch-no-encode-headers'

The output from "git format-patch" uses RFC 2047 encoding for non-ASCII letters on From: and Subject: headers, so that it can directly be fed to e-mail programs. A new option has been added to produce these headers in raw. * eb/format-patch-no-encode-headers: format-patch: teach --no-encode-email-headers
