Sigh.  I just realised that I replied to 3 of the postings directly to 
the poster, rather than to the list.  Bloomin' Thunderbird default.

Just so people don't think I'm ignoring all the (incredibly) helpful 
replies, I'm copy+pasting said replies below, and my apologies for any 
confusion.  Blame it on 3 days of flu.
