One problem with such simplicity is that you need to define what an
"action" is. If I make a commit, the undo is probably "reset HEAD@{1}".
If I fetch a ref, would undo move backwards? What if I fetch multiple
refs with one command; do we undo all of them? How about during a
multiple-command operation, like a rebase? Does an undo affect the last
commit, or the whole rebase?
I think these questions can be answered (though I am not sure of the
best answer for most of them, nor even if there is a single answer that
covers all situations), but I think a starting point for any "undo"
command would be coming up with a list of what constitutes an action,
how we record the list of actions, and then an appropriate "undo"
reaction for each action.
