Okay, I'll disable that particular mirror tonight and let rsync do its
stuff.  Even if most of the site does get refetched for some reason,
it shouldn't hurt too much.  :)

I piped the output of my dry run into a file, and had a look at it a
bit later to see what rsync had to say ...

I would say that my mirror.pl -maintained mirror isn't up to snuff, as
lots of things look like deleting them is the correct thing.

Okay.  :)

Well, I'm reasonably confident that rsync will do a better job than
mirror.pl (whose time is pretty much up, in my unvaunted opinion).  I
have started rsync for real now (no more dry runs) and I'll watch its
progress as it continues to update the mirror over the next few days ...
