git-rebase: make 'rebase HEAD branch' work as expected.
When you want to amend the commit message of 3 commits before the tip of the current branch, say 'master', A--B--C--D--E(master) it is sometimes handy to make your head detached at that commit with: $ git checkout HEAD~3 ;# check out B $ git commit --amend ;# without modifying contents... to create: .B'(HEAD) / A--B--C--D--E(master) and then rebase 'master' branch onto HEAD with this: $ git rebase HEAD master to result in: .B'-C'-D'-E(master=HEAD) / A--B--C--D--E However, the current code interprets HEAD after it switches to the branch 'master', which means the rebase will not do anything. You have to say something unwieldly like this instead: $ git rebase $(git rev-parse HEAD) master This fixes it by expanding the $onto commit name before switching to the target branch.
