addnickchasetomodenick.patch

   1 ircu uses nick chasing for whowas, but also for targetting /kill, /kick, /mode o/v, in case a nick isnt found, the whowas history is check and the intented victim is chased (time limit is 30 seconds)
   2
   3 example without this patch:
   4 00:01 > NICK newnick
   5 00:01 > MODE oldnick +w
   6 00:01 < oldnick!user@host NICK newnick
   7 00:01 < irc.quakenet.org 403 newnick oldnick :no such channel
   8 usermode change failed because of the nick change getting in the way
   9
  10 example with this patch:
  11 00:01 > NICK newnick
  12 00:01 > MODE oldnick +w
  13 00:01 < oldnick!user@host NICK newnick
  14 00:01 < newnick!user@host MODE newnick +w
  15 usermode change succeeded because ircd uses whowas history and found the previous user with this nick was this user
  16 much friendlier and simply achieved by using information already available
