To provide metadata from svn dumps for further processing, e.g.
branch detection, attach a note to each imported commit that
stores additional information.
The notes are currently hard-coded in refs/notes/svn/revs.
Currently the following lines from the svn dump are directly
accumulated in the note. This can be refined on purpose, of course.
- Revision-number
- Node-path
- Node-kind
- Node-action
- Node-copyfrom-path
- Node-copyfrom-rev
