For some unknown reason to me, our developers started a git project,
called Ver1, this was the first version. Then sometime later, they
created a new git repository called Ver2, the initial commit for Ver2
was essentially a copy of the code in Ver1 from the master. They
didn't clone it, they just copied the code at the latest point.
This is why "graft points" were created, and then superseeded by "git
replace".
