Heyla,
   while my previous patch (message 867) did provide a solution in 99.9999999%
 of the cases, there is logically one (obscure) bug which noone will ever, ever
 come across, but...  Anyway, the most elegant solution to the problem happens
 to be very similar to the original quick & dirty hack I thought of but didn't
 want to use - ah, well, you can't win them all.  
And we hope rc's still alive and bringing us 2.6.14 soon.

This goes on top of 867.
seeya, 
 Geoff  (trying to make zle_refresh 100% robust).
