Rebasing can get quite tiresome in the long run. It's like 7 steps, and that's without the merge conflicts someone with my luck is guaranteed to run into.

I couldn't quite tell one way or the other, but I think that the original poster was asking about the case in which one wants to move some hunks out of one commit and into an earlier one.
I usually go about this with something like:
h="$(git rev-parse HEAD)"
git reset HEAD^
git add <file[s]> # re-stage the files that you want to move "up"
git commit --fixup <hash>
git add --all .
git commit -C "$h" # "re-apply" the commit that you were moving out of
GIT_SEQUENCE_EDITOR=true git rebase -i --autosquash

My preference is usually to allow 'git rebase -i' to open my "$EDITOR" and change the todo list to "reword" for any commit(s) for which I want to change the message.
