[NOTE]
Most likely, you are not directly using the core
-git Plumbing commands, but using Porcelain like Cogito on top

-have to run `git-update-index` yourself for changed files (you
-do tell underlying git about additions and removals via
-`cg-add` and `cg-rm` commands). Just before you make a commit
-with `cg-commit`, Cogito figures out which files you modified,
-and runs `git-update-index` on them for you.

Sometimes you may wish to create a new branch _without_ actually
checking it out and switching to it. If so, just use the command
`master` branch, and the second column for the `mybranch`
branch. Three commits are shown along with their log messages.
All of them have non blank characters in the first column (`*`

There are (confusingly enough) `git-ssh-fetch` and `git-ssh-upload`
programs, which are 'commit walkers'; they outlived their

Once you fetch from the remote repository, you `merge` that

It should be stressed that this hierarchy is purely *informal*.
There is nothing fundamental in git that enforces the "chain of
