Comment 4 for bug 177809

To find the thread, look for 177809 in the list archives from early 2008.

The patch foundered over the location of the code and [less so] the manner of the approach.

Just noting this here to help folk coming to work on it.

Personally, I'd be inclined to change bzr to plan the rename, create a tree transform of it, and apply it. That would allow tree transforms rollback etc logic to be used and perhaps shrink some duplicate code.
