Great; that works.
Is that procedure supposed to be the usual way I track upstream in this
(1.7) version of git? It seems arcane.
I had thought the usual workflow was supposed to be one of 2
git checkout remotes/origin/master
git pull origin master
git checkout master
git merge remotes/origin/master
But that failed on the first step. Or
# assuming we are on the local master branch
git fetch origin master
# and everything is updated.
Is the problem that I called the local branch with my modifications
master instead of something else?

After studying man git-fetch's discussion of the refspec parameter,
especially the second note:
You never do your own development on branches that appear on the right
hand side of a <refspec> colon on Pull: lines; they are to be updated by
git fetch. If you intend to do development derived from a remote branch
B, have a Pull: line to track it (i.e. Pull: B:remote-B), and have a
separate branch my-B to do your development on top of it. The latter is
created by git branch my-B remote-B (or its equivalent git checkout -b
my-B remote-B). Run git fetch to keep track of the progress of the
remote side, and when you see something new on the remote branch, merge
it into your development branch with git pull . remote-B, while you are
on my-B branch.
I'm even more confused. Is "Pull: lines" a reference to log messages
during the fetch, a configuration file, or something else? The docs
refer to a pull: line in $GIT_DIR/remotes, but I have no such directory.
I do have .git/config, which includes
url = https://github.com/RossBoylan/ESS.git
fetch = +refs/heads/*:refs/remotes/personal/*
remote = personal
merge = refs/heads/master
url = https://github.com/emacs-ess/ESS.git
fetch = +refs/heads/*:refs/remotes/origin/*
Ah! branch master is associated with the personal remote; is that why
updating it from origin's master branch has no effect on origin/master?
I also don't know what the "." in "git pull . remote-B" does; the
git-pull manpage doesn't indicate it's legal as far as I can see.
