As some of you are using my git configuration, there's an updated version now, that includes a short version of --pretty=oneline option for git log, which is very useful if you want to get a quick impression on what is going on. Thus the new short commands are (just an o added at the end):

git lo
git lco
git lpo
git lpco

Furthermore I added the following new short commands:

git m (merge)
git pl (pull)

Have fun, other lazy people like me!
