Correct. (If you use "git send-email" it'll do this automatically.)

e.g., trimmed from my workflow:

git format-patch -n --to "$to" --cover-letter -o outgoing/ \
	--subject-prefix "PATCH v$version" "$SHA"
edit outgoing/0000-*
git send-email --transfer-encoding=8bit --8bit-encoding=UTF-8 \
	--from="$ME" --to="$to" --cc="$ME" --cc="...more..." outgoing/*
