I've managed to muck up a commit message bad enough, that when I read it back, even I can't work out what is says!
This commit hasn't been pushed and I know that the message can be changed with:
git commit --amend -m "New commit message"
(thanks to this post)
However, I am using the GitHub for Windows GUI. So is there any way for me to change the commit message without jumping into powershell?
Aside from rolling back the entire commit and recreating it this is not possible in the UI. Rolling back performs an equivalent of git reset HEAD^
