Better handling of search lines in resolv.conf

I'm a new user of cfengine, I'm using version 2.0.2.
In our environment we have a nameserver configuration that contains
a line like
   search zurich.ibm.com ibm.com
Using the resolve action, this line is left untouched, but another
search line is added, so the search statements read like:
   search zurich.ibm.com
   search zurich.ibm.com ibm.com
I suggest a small change in do.c to improve this handling:

+if ( LocateNextItemStarting(filebase,VBUFF) != NULL )
+  printf("File %s has already a line starting
+  PrependItem(&filebase,VBUFF,NULL);

 snprintf(VBUFF,bufsize,"domain %s",ToLowerStr(VDOMAIN));

With this patch, the resolve action will look for search statements
starting with "search mydomain" and will leave those lines untouched,
otherwise it will add an appropriate line.
