And if you just want do have a local branch, to do your work in and
still want to enforce linear history, you can use the same workflow as
Phil described. You just need to "replay" your changes on top of
"master". "git rebase" does that.

Switch back to the feature branch:

  % git checkout feature_foo

Rebase the feature branch on top of new changes that were just pulled:

  % git rebase master

This does the following (ASCII graphs from git's manual):

 Commit situation before the rebase:

                  A---B---C topic
                 /
     ...    D---E---F---G master

 And after:

                         A'--B'--C' topic
                        /
     ...    D---E---F---G master

This essentially replays the commits from the topic (or feature) branch
on top of master. That creates commits with different SHA1 sums, hence
the apostrophes with the rebased branch.

That merge is a fast-forward then, because it just involves putting the
pointer of the master branch to the tip of the topic branch; because its
linear history again - no real merges involved at all.

Those are actually pretty helpful indeed.
