Here's the scenario: I've made a substantial number of changes to my project so I add, commit, and am ready to push. Then, right before pushing, I remember that I need to change 1 line of the README.
I would like to not have to make a separate commit just for the README edit. Is there any way to either
A. Add to the commit I already have
B. Remove the previous commit, combine everything into one commit
This happens fairly often, and I've always just made two commits, but having just one would be great!
