type in cg-merge?

I am just reading the code in cg-merge to see how it works (taking your advice 
to see how to re-write my history properly - see early threads about this 
subject)

At line there is an echo 0 that looks suspiciously like it should be an exit 
0.

Of course I may just have egg on my face - its my first attempt at looking at 
the code.
