From: Niko Tyni <[email protected]>
There's currently no notes filter for git-filter-branch, so we need
to use the commit filter instead.
---
only small changes from Niko's second version:
- add notes also to stdout exported patches (mbox)
- some newlines to debugging output
- add some comments to the parts that initially puzzled me
The revised version seems OK to me.
