name  Unregister:
<<syntax>>
<<Unregister fullPathName>>
<<A Commander.Lookup[fullPathName] is done.  If the name exists, then the name is re-registered with a NIL CommandProc, effectively 
wiping out what was there before.>>
<<description>>
<<Unregister a command, so that it can no longer be invoked.>>
<<examples>>
<<% Unregister Alias
Unregister: Alias not found
% Unregister ///Commands/Alias
% Alias
[[Alias . . . not found]]
% >>
<<warnings>>
<<Unregister just sets the proc field of the stored record to NIL, so that clients of Commander.Lookup must be careful to check 
that the proc field of the CommandProcHandles returned by Lookup are not NIL.>>
<<Someday, this command may merely rename these to-be-deleted commands into another "directory" from which they can be retrieved.>>
<<stop/undo >>
<<Probably too fast to stop.>>
<<implementation >>
<<InitialCommandsImpl.mesa in CommandTool.df>>
