Thank you for this.  However, I managed to find a disaster in there 
despite everything.  :o(

I renamed the whole e:\cygwin tree to e:\old_cygwin.  I had to rerun the 
install several times, for reasons I need not go into.  Eventually it 
got to the end and said "I found an old cygwin, shall I delete it?"  I 
assumed it meant one from the immediately previous installation, which 
had also completed, but with errors, so innocently pressed "OK". 
Mistake.  It deleted the whole e:\old_cygwin tree, including a load of 
stuff that wasn't actually cygwin at all and was only there for 
historical reasons.

And none of it is recoverable, nor backed up, of course.  Boo hoo.
