* lisp/org.el (org-time-string-to-seconds):
For deadline and scheduled agenda display ignore the cyclic repeater
when calculating how many days late the task is.  If you have a weekly
task and miss the date the agenda view will show more than a week late
now instead of resetting on the cyclic repeating date.  This makes it
much more obvious when you missed a repeating task after the repeater.

Thanks to Bernt Hansen for this patch.
