git log --graph in the face of vendor imports

[Philip Paeps]

I have this alias to make `git log --graph` meaningful:

```
[alias]
         llog = log --graph 
--pretty=format:'%C(yellow)%h%C(red)%d%Creset %s %C(blue)- %an, 
%ar%Creset'
```

I noticed that in our repository, the graph shifts farther to the right 
with each vendor import.  Is this expected behaviour?
