Incorporates changes into the current branch. By default the upstream branch is
used, but a different commit can be specified in the arguments.
+Assume the following history exists and the current branch is
+`master`:
+
+------------
+ D---C---B---A origin/master
+ ^
+ |
+ master
+------------
+
+Then `git fast-forward` will advance the local `master` to `origin/master`:
+
+------------
+ D---C---B---A origin/master
+ ^
+ |
+ master
+------------
+
+This operation is not always possible; if you've made changes and the branches
+diverged:
+
+------------
+ D---C---B---A origin/master
+ \
+ X---Y master
+------------
+
+then the fast-forward command will fail.
+
+In those cases you need to either `git merge`, or `git rebase` in order to
+synchronize the two branches.
+
THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOUR MAY CHANGE.
