Consider branching for each feature, as it can be quite annoying to
keep a branch in sync with master all the time. Merge conflicts

Feature (or bugfix) branches also have the benefit of letting you do
many small commits with good log messages, then squashing the feature
back to master in one commit that describes the whole feature:

git checkout master
git merge --squash my-feature  # where my-feature is the name of your
feature branch

You then keep the feature branch around for the nice granular commit
messages, should you need them in the future.

You want this:

git cherry-pick 160ef92

If so, I guess it needs to be done in the branch spec in your
.git/config. I don't know how to do it, though.

Right. Almost every git command needs a reference, or silently applies
a default. I guess "reset" defaults to HEAD^.
