Spectator kill exploit

I've forgotten the link to the web CVS for the Quake 2 code.  Can someone
remind me again so I can book mark it this time?

Regarding the spectator kill exploit again - I still can't reproduce this
bug, but I believe someone with a hacked client can crash a server by killing
themselves while in spectator mode.  Someone confronted the person (the only
person who has been observed using this exploit) about it, and the user acted
innocent... and of course crashed the server as usual.  (This is the fourth
time Chattanoo has been observed crashing the server and a ban only lasts
until the IP changes).

Regardless of if the attempt is malicious, this can be prevented by the check
in the kill command to return early if a spectator has typed (or pressed a
bound button to) "kill"

Someone sent me a client condump below which confirms the crash. I believe
this is patched now in the game code for icculus.org but I have misplaced the
link to the web CVS to verify the patch has been made.  I recommend patching
this if you run a public server.  The server I'm trying to get patched is
"arena.xquake.net" which is running a Linux game.so
