I was interested in participating in an open source project, and I happened to come across Koji while looking around. To get myself started, I decided to look at the active tickets and fix one of them. In this case, Ticket #41 add --lines= and --tail to watch-logs. I am pretty new to this, so I picked something a little easier. Attached is my patch. If you have any suggestions for improvements I would be very appreciative of it.
