It's a pretty typical triangular workflow, with a touch of fork maintainership.

Here are some types of branches I have:

* master [origin/master, gh/master] Git 1.9.1

My main master branch, I use it as a base point for many other branches. I
don't use origin/master because that's a moving target.

* dev/remote/hg-extra [master] remote-hg: store extra hg information in notes

A development branch. I don't publish those, therefore no @{publish}.

* fc/publish [fc/branch/nice-verbose, gh/fc/publish] sha1_name: add support for @{publish} marks

A branch that is all good. I publish those, and use them for git-fc (my fork).
I think they should be in Git's core, but haven't been merged for some reason
or another.

Notice that the upstream branch is another local branch, not master. Strictly
speaking it's not an "upstream" branch, but I want 'git rebase' to use that as
the base point. Another @{base} concept might be more appropriate, but those
patches are a different story.

* up/publish [master] sha1_name: add support for @{publish} marks

A branch that should be sent upstream. I don't publish those.

Notice up/publish is different from fc/publish because the later depends on
another fc/* branch, which wasn't accepted upstream.

* fc/master [gh/fc/master] prompt: fix missing file errors in zsh

My main branch, used for git-fc. I merge Git's master, and cherry-pick various
fixes, so it has always the latest and greatest stuff.

Notice that 'gh/fc/master' is the publish branch, there is no upstream.

* pu [] Merge branch 'travis-ci' into pu

Similar to Junio's pu, I use `git reintegrate` to generate this branch using
'master' as the baseline, and merging all the fc/* branches. The result should
be identical to fc/master, if not, we are missing something from upstream, or
there's something missing in the fc/* branches.

It's not published, and has no upstream.


As you can see; some branches are published, others are not. The ones that are
not published don't have a @{publish}, and `git branch -v` doesn't show them.
Why is that hard to understand?
