If you want to squash a commit series, the magic is git rebase -i. You
give that a number of commits to look back at at and you'll get a buffer
instructing you how to squash and shuffle that series.  You'll also be able
to edit the commit message.

I like to write really fine-grained commits when I'm developing, then
squash before pushing so the public repo commits always go from "tests
pass" to "test pass".  That way you can do clean bisections on the
public history.

There are a couple of ways.  I usually squash as described above
then use "git cherry-pick".  But that's because I have philosophical
reasons to avoid long-lives branches.

Yes, in general you'll want to do that.

I do it at rebase -i time along with the squash of the series.
