format-patch -s: add MIME encoding header if signer's name requires so

gitster · gitster · commit 4593fb84051d · 2007-11-01T17:18:39.000-07:00
When the body of the commit log message contains a non-ASCII character,
format-patch correctly emitted the encoding header to mark the resulting
message as such.  However, if the original message was fully ASCII, the
command line switch "-s" was given to add a new sign-off, and
the signer's name was not ASCII only, the resulting message would have
contained non-ASCII character but was not marked as such.
