Thanks for the reply. I think I might get it, though playing 'spot the difference' between two sets of source code is making my eyes water. Are you saying that the code:
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> is what generates the tiny up caret in the top left of the dropdown? I've deleted this code (lines 6-10) in the Bootstrap demo source and it makes no difference at all to the document that I can see - the top navbar remains the same, and the up caret appears in the dropdown. To be honest, I'm damned if I can see what the empty spans are for. Or is there some code in the dropdown I'm missing?
