Hi,
$ git log --first-parent --oneline origin/master..origin/pu
and find "Merge branch 'rr/remote-helper-doc'" in the output. The second
parent of that merge commit (e.g. 6144af5^2 == ad466d1) is the tip of your
topic. You can verify it with:
$ git log -p origin/master..ad466d1
$ git checkout -b remote-helper-doc ad466d1
... build further on it ...
Thanks for the excellent instructions. I'm just curious: why didn't
you include these instructions in your rewrite of SubmittingPatches?
