Here is a simplified version of my script. It does only the merge. If
you want to use it, I recommend adding this script to a separate branch
so that you can track which branched were added or removed to your
features branch (you will modify the $branches variable in the script).

#!/bin/sh

branches="
decode-headers-in-reply
dme/citation-suffixes
no-self-bcc-on-reply
"

set -e

die()
{
	echo >&2 "fatal: $*"
	exit 1
}

if [ -z "$EXEC_OK" ]; then
    # If this script is tracked by repository, checking out another
    # branch could delete it so we copy it to tmp and run it from
    # there.
    script=$(mktemp -t notmuch-integrate.XXXXXX)
    cp "$0" "$script"
    EXEC_OK=1
    export EXEC_OK
    exec sh "$script" "$@"
fi

[ $EXEC_OK != 1 ] && die "Error: something went wrong"

trap "rm '$0'" EXIT

git branch -D integration/features || :
git checkout -b integration/features master
git merge $branches
