Subject: Prevent switching branches when local modifications exist
Message-ID: <h5ina9-g9n.ln1@homer.bruehl.pontohonk.de>

Hi,

how can I prevent that git allows me to switch branches when there are 
uncommited local modifications?

[14.1 (steiner_topo)]$ git checkout -b ergo
Switched to a new branch 'ergo'
[14.1 (ergo)]$ echo blub >> src/invtree.C
[14.1 (ergo)]$ git checkout steiner_topo
M       src/invtree.C
Switched to branch 'steiner_topo'
[14.1 (steiner_topo)]$ 

How can the last checkout be prevented?
