I know that.  Don't take my questions as indications that I'm
unfamiliar with basic git terminology (I was once, but no more).

I was talking about the defaults.  For the defaults, the important
question is what would J. R. Hacker want in most of his commits.  It
seems to me that occasional contributors to projects (as opposed to
their core developers) will seldom if ever get to the complicated
workflows you describe.  It's definitely true for me in a couple of
projects in which I'm involved (not Emacs, obviously).

Well, let's begin by agreeing that what you described is just bad
habit: you should commit very frequently, and so seldom if ever get to
the point where you have hacked for a day and a half without a single
commit.
