New Revision: 10655
URL: http://svn.gna.org/viewcvs/etoile?rev=10655&view=rev
Log:
Revert 'COUndoTrack: migrate -undoNode:,-redoNode: to use the new
-addToStoreTransaction: method in COCommandGroup instead of -applyToContext:,
and remove -applyToContext: because it is no longer used. This eliminates two
parallel implementations of the complex logic in
COCommandSetCurrentVersionForBranch.'. See comment inserted in -[TestUndo
testSelectiveUndoOfCommands2]
