There seems to be a bit of problem with "git mailinfo" with this
patch.  No need to resend this series, as I think I can cope, but to
solicit help from folks diagnosing and fixing the issue with the
"git am" pipeline.

You've been sending your patches as "multipart/signed" (which by the
way was cumbersome enough for me but that is primarily the problem
with Emacs/GNUS and we should handle multipart/signed well), whose
header reads like so:

Content-Type: multipart/signed; micalg=pgp-sha512;
	protocol="application/pgp-signature"; boundary="ovDSRLSkA00eIgbN"

The "message" part in it says that it is encoded in iso-8859-1:

    --ovDSRLSkA00eIgbN
    Content-Type: text/plain; charset=iso-8859-1
    Content-Disposition: inline
    Content-Transfer-Encoding: quoted-printable

    ...

But the source in t/t4210-log-i18n.sh actually is written in UTF-8.
The thing is, the "-u" option (recode into utf-8" is supposed to be
the default for "git am", and it is passed down to the underlying
mailinfo machinery in builtin/am.c:parse_mail().

But apparently that is not working correctly.  I see in the patch an
unrecoded byte E9 in the resulting patch file that is fed to the
underlying "git apply" machinery, failing the application.

ANyway...
