WC-NG 3-trees description [was: '@BASE' vs. 'BASE tree']

Any WC-NG folks prepared to comment on this? We should put this
description in note/wc-ng/... if it's OK.

Re: WC-NG 3-trees description [was: '@BASE' vs. 'BASE tree']

That page looks good.

On the definition of trees, the second para is correct: the path
changes for a renamed node. There will be an NG-WORKING node recording
"moved-away", and another NG-WORKING node recording "moved-here". An
NG-BASE node will be present for the original path, but will not exist
at the new path.
