See my git text, look for "squash" and "fixup" -- I also have a
description of such "checkpoint commits" and how they can be squashed
away before you push the final product.  (And I wrote that description
mainly because I had your use case in mind.)

You probably mean "HEAD~10".

But again, see my text -- you don't need to count commits, instead
just use

  git rebase -i origin

which will show you all of the commits you have over the origin/master
branch for reorganization.

Looks like you know what to do with that now, but just to summarize:
any kind of history rewriting means that people will have problems
updating -- in the case of robby/plt this is easy since "people" is
only you, and you never need to worry about combining stuff if you do
it only when you move between machines.

It's only when you want others to use it that you need to be careful.
(For example, Matthew warning people that he's occasionally rebasing
the gr2 repo.)
