Graft mark as renamed all files touched by plugin

In graft you can see ->:

1### issue metadata added
2
3b505ee382eedd7de0243fae7fd0292fe6eabb417
4
5- -> [issues/300525-fix-some-wording.md](../issues/300525-fix-some-wording.md)
6- +- [issues/300525-fix-some-wording.md](../issues/300525-fix-some-wording.md)

But ladydug has not renamed file.

I think gitroot put a "" (emtpy string) has oldPath in modFile(oldPath, newPath) method for others plugins.
