Maybe.  The only widget where the duplicates make sense is the command
line (the history is shown by Alt-h on the panels).

But I think I can live without duplicates even for the command line.  
Removing the duplicates makes the history shorter.  If I want the complete
history, I can switch by Ctrl-O to the subshell and browse its history.

If anybody will seriously miss full history with duplicates in any widget,
please explain the reason.
