git swap - swaps top two commits; git drop [revision] - nukes that revision (or HEAD); git hoist <revision> - rebases that revision to be the most recent commit, so you can tweak it
[alias]
swap = "!GIT_SEQUENCE_EDITOR=\"sed -i '' -n 'h;1n;2p;g;p'\" git rebase -i HEAD~2"
drop = "!f() { GIT_SEQUENCE_EDITOR=\"sed -i '' '/^pick '$(git log -n 1 --pretty='%h' ${1:-HEAD})/d\" git rebase -i ${1:-HEAD}^^; }; f"
hoist = "!f() { GIT_SEQUENCE_EDITOR=\"git log -n 1 --pretty='pick %h' $1|~/bin/hoist-lines.pike\" git rebase -i $1^; }; f"
