When using compact format, gtop->root is always overwritten
by the 2nd argument of gtags_open.

  322         if (gtop->format & GTAGS_COMPACT) {
  323                 assert(root != NULL);
  324                 strlimcpy(gtop->root, root, sizeof(gtop->root));

The thing which I want to know is when an empty string("") 
is specified by the 2nd argument of gtags_open.
If it never happen, this check will be meaningless.
