lineinfile: dest=/etc/rsyslog.conf insertafter=“\*.\*;auth,authpriv.none” regexp=“\*.\*;auth,authpriv.none” line=“Listen 8080”

The only thing that happens here is Listen 8080 replaces the _._;auth,authpriv.none line. should it not be placing it after it???

I think you don't need the regexp, or rather the regexp should match  
the line you are \*inserting\*. To let ansible know, if the line is  
already in there.

Right now you are telling ansible to replace the line  
...auth,authpriv... and insert the line after the line ...auth,authpriv...
