[syslog-ng] syslog-ng-1.9.6 template bug patch

[Peter Nahas]

I have stumbled upon a bug in syslog-ng-1.9.6 caused by an un-cleared 
buffer in logwriter.c which causes templated messages to be output 
improperly.  Up until a certain point (not certain why it stops, perhaps 
due to a buffer size?), for each message output, all previous messages 
are output.  For example, if the messages "One" "Two" and "Three" are 
sent to syslog-ng, the destination will receive "One" "One" "Two" "One" 
"Two" "Three".  I have included a patch which solves the issue, but 
there may be a better solution.  If you want a syslog-ng.conf which will 
produce this issue, let me know.

Thanks,
