For *Buffer List* maybe was OK that old way.  My concern is that
`tabulated-list' is still a young lib (2011) in an Emacs scale and
a general tool;  that funny truncations might look uglier in future
applications using this lib.

Thanks for this suggestion.
This might be good: we get generally longer truncations.  I am
not sure how it looks in big tables, but i can test it.

I will prepare a patch for this alternative truncation.
