[RFC] git-float

Hi! Here's a simple script I use to float a commit up the history - similiar to what stg float does if I understand it correctly.

Is this a good way to implement it? Would it make sense to have something like this in git tree? Drop me a note.

#!/bin/bash

check_revision() {
	case $# in
	2)
		true
		;;
	*)
		echo "Unable to float $1: it does not match a single non-merge commit" >&2
		exit 2
		;;
	esac
}
ref=`git-rev-list --no-merges $1~1..$1`
check_revision "$1" $ref

git-rebase --onto $ref~1 $ref && git-cherry-pick $ref
