"""WorkingTree object and friends.
19
A WorkingTree represents the editable working copy of a branch.
20
Operations which represent the WorkingTree are also done here,
21
such as renaming or adding files. The WorkingTree has an inventory
22
which is updated by these operations. A commit produces a
23
new revision based on the workingtree and its inventory.
25
At the moment every WorkingTree has its own branch. Remote
26
WorkingTrees aren't supported.
28
To get a WorkingTree, call bzrdir.open_workingtree() or
29
WorkingTree.open(dir).

# copy, and making sure there's only one WorkingTree for any directory on disk.
39
# At the moment they may alias the inventory and have old copies of it in

Preserve the wt.basis->wt.state changes

Transform the wt.basis to the new master basis.
1361
Apply a merge of the old branch basis to get any 'local' changes from it into the tree.
1362
Restore the wt.basis->wt.state changes.

There isn't a single operation at the moment to do that, so we:
1365
Merge current state -> basis tree of the master w.r.t. the old tree basis.
1366
Do a 'normal' merge of the old branch basis if it is relevant.
