[PATCH 4/4] rebase -i: use "git sequencer--helper --fast-forward"

[PATCH 4/4] rebase -i: use "git sequencer--helper --fast-forward"

[Christian Couder]

when fast forwarding.

Note that in the first hunk of this patch, there was this line:

test "a$1" = a-n && output git reset --soft $current_sha1

but the test always failed.

	The test "a$1" = a-n fails because if "$1" is set to "-n"
	then "$no_ff" is set to "t" above by:

	case "$1" in -n) sha1=$2; no_ff=t ;; *) sha1=$1 ;; esac

	and that means that:

	test "$no_ff$current_sha1" = "$parent_sha1"

	will fail.

	But maybe I missed something. Otherwise I can send a patch
	for master to remove the dead code.
