Using Gerrit without git-cl

setup

creating a change

Create a topic branch
```
git checkout -b TOPIC -t origin/master
```

Make some commits.

echo 1 > whitespace.txt
git commit -a -m 'Change Foo'
echo 2 > whitespace.txt
git commit -a -m 'Change Foo again'

Squash the commits:
```
git squash-commits
```
This is only needed if you have more than one commit on your branch.
Push to Gerrit
```
git gerrit-push-master
```

updating a change

Edit your commits more.
```
echo 3 > whitespace.txt
git amend-head
```
Re-squash if needed. (Not needed if you only amended your original commit.)
Push to Gerrit.
```
git gerrit-push-master this is a message
```
The title of this patchset will be "this is a message".
