The best person to direct questions to about the PIM implementation is 
probably the original author, Pavlin Radoslavov. However, he is quite a 
busy guy.

Reading around that code (which I'm not directly familiar with and took 
a little while) it seems that the code you're discussing is correct.

If the WC bit is set on a pending PIM join-prune, it means the group is 
in (*,G) (any-source) mode, therefore it makes no sense for the sources 
to be sent for that group to a PIM-SM peer in the join-prune message.
