Which line of code can I remove to stop cloning the tag line of the new blog template?

I've done some custom coding that alters the tag line of new blogs, such that it is slightly different on each site... but new blog templates is overwriting it of course. I'm looking around in the plugin code to see if I can just surgically remove that part of the cloning commands responsible for the tag line. Anyone familiar enough with the code to help me out?
