Hi Chris and all,

the world state's "stepList" is fine, because the entries will be removed
before processed and then only re-added if the processing went well. See
WorldState >> #runLocalStepMethodsIn: and all references to the instance
variable "lastStepMessage" to understand why it can be nil after evaluating
it.

A world state's "commandHistory" can be cleared via the menu Extras > "Purge
Undo Records". This is also done in CommandHistory class >> #cleanUp. If you
collect garbage via "Utilities garbageCollectAndReport", you get notified of
any records in the history.

Memo to myself: I still have to bring CommandHistory and
TextEditorCommandHistory back together.

Best,
Marcel
