Re: [RFC] git-split: Split the history of a git repository by subdirectories and ranges

You are handling grafts by hand because --pretty=raw is special
in that it displays the real parents (although traversal does
use grafts).  Maybe it would have helped if we had a --pretty
format that is similar to raw but rewrites the parents?

I have wondered recently why grafts are hidden in this way.  I feel they
are something I want to know is occuring in my history as this history
is being manipulated.

Just to make sure we are on the same page, only "raw" format
output is special and it is special only on output.  Ancestry
traversal always honors what you have in grafts.

However, you can do:

$ git rev-list --parents --pretty=raw

which would give you "commit $this_commit $its $parents" lines
and "parent $true_parent" lines at the same time.

And they will be inconsistent when you have grafts or path
limiter.  The former honor grafts and path limiter, and the
latter show the true set of parents.
