+    Dynamically allocate the log buffer to prevent warning messages
+    
+    On anoncvs.opensource.apple.com (Apple's anonymous CVS server for
+    WebKit), some very long log entries were included in CVS.  I got tired
+    of cvsps-2.1 truncating them, so I made the 'logbuff' buffer be
+    dynamically allocated.
