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.
