Oops, sorry if I was unclear. This happens in config.c here,
http://git.kernel.org/?p=git/git.git;a=blob;f=config.c;h=1fc063b2562101687b9215e5b697a91fcffdd5bb;hb=924aaf3ef764a5e8e976f68e024ecacf54ff6306
  
This happens once the file is opened successfully here,
  1449         if (!(config_file = fopen(config_filename, "rb"))) {
and then you enter the while loop here,
  1454         while (fgets(buf, sizeof(buf), config_file)) {
and then you take any 'goto out;' in the while loop, which doesn't
close the file handle.

1505  out:
1506         free(config_filename);
1507         return ret;
1508 }
