git-mailinfo fixes for patch munging

Don't translate the patch to UTF-8, instead preserve the data as
is.  This also reverts a test case that was included in the
original patch series.

Also allow overwriting the authorship and title information we
gather from RFC2822 mail headers with additional in-body
headers, which was pointed out by Linus.
