:OK. I've found the problem (and another smaller one - the code gets to a 
:place I commented as 'shouldn't happen' - now I've got to remember why :-)).

I am still not totally sure why I had it commented as `shouldn't happen'.
Most likely it would have had to do with cleareol stuff and it may be
redundant, but since it may not I've left it in.

:Patch in a day or so.

Or a bit longer.
