Oh, Father Christmas, my blessings on you fall, for bringing him a big, red, 
India rubber ball!

Thank you so much, all of you for your extreme patience and helpful attitude.  
This really is a *super* list.

This is better than an India rubber ball, even a big, red one.  I now have 
loads of space in a partition that is never as much as 10GB, and still have 
some cruft which I intend to cull, having had it pointed out to me by you 
lot.

I didn't know about the --max-depth=1 option, and my attempts to do this 
without the depth limit gave me so much overkill, that I couldn't see the 
wood for the trees.  I even got as far as realising that Distros were in some 
way implicated, without the penny dropping.  Doh! :-(

I now know why the system did not warn me - it didn't get a chance.  I knocked 
it right up by 22G all in one fell swoop.  I ought to have realised that this 
was the problem.  I won't embarrass myself by telling you what I thought I 
had done.  I have put myself in a corner with a dunce's cap on.

See below for my recent activity.

Now I shall get down to using all the other suggestions.  There is still some 
cruft to be explored.
