I'd second that. git cherry-pick is very useful. The other tool I use a
fair bit is `git merge --squash` when I want to compact the contents of
a messy working branch down to a single commit. I usually prefer to `git
rebase --interactive` the working branch to clean it up then `git merge`
it into the target branch, but that isn't always practical.

The main thing I find to be important is to maintain clear, discrete
units of work, not change sets that fix X and Y and add Z. That way you
can easily keep track of the fact that change <x> is in branches A, B and C.
