[PATCH 1/2] hooks/post-receive-email: set encoding to utf-8

From: Gerrit Pape <redacted>

"git log" generates logs in UTF-8 encoding by default, but the
post-receive-email example hook does not declare any encoding in
the emails it sends.  So add a line there:

+	Content-Type: text/plain; charset=utf-8

[jn: tweaked to also set the Content-Transfer-Encoding so MTAs know
what kind of mangling might be needed when sending to a non 8-bit
clean SMTP host]
