bgp:change in showing neighbor description

currently "show bgp summary" and "sho bgp summary wide" commands
provide a description string until a whitespace is occuring this
respectively with size limits of 20 and 60 chars

now theses two commands are providing strings with all
characters until the last witespace before size limit
