symlink chain.

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

I just noticed that 'whence -s' very quietly 'finishes' a chain of 
links, and shows you the final target.  'ls' OTOH only ever shows you 
the first link in a chain. It gets me wanting some way of showing an 
entire chain of links where that applies.  Can it be done? It occurred 
to me that perhaps 'whence' should not use the standard " -> " symbol 
when showing a link, because it's not a normal display, but a jump to 
the end of the chain.  Dunno, is there a better symbol for that?  " ->> 
" or something?

BTW Peter, Oliver, finished the book, thanks again, it was very helpful, 
the only thing that defeated me was the chapter on completion.
