bug#11388: 24.0.95; Improper kill-line in zone.el

Date: Tue, 1 May 2012 10:13:52 -0400

I noticed that my last kill and the desktop clipboard were being
overwritten when Emacs was zoning.  This is because one of the zone
programs uses kill-line.

Reproduce with:

(let ((zone-programs '(zone-pgm-stress)))

Here's a patch:

2012-04-25  Aaron S. Hawley  <address@hidden>

        * zone.el (zone-pgm-stress): Use delete-region instead of kill-line
        unless munging the kill ring is part of the "stress".

Thanks for Emacs.
