  The point became moot; I committed the rest of the patch (which had all been
approved for some time) before stage3 ended.  This bit is still outstanding;
as there's a choice between two proposed patches for this problem I'm pinging
this patch so that both it and Iain's are at the top of the current threads
for quick reference.

  Just so everything is nicely cross-referenced, Iain's alternative approach
is posted at:
