"unexpected operator" in have_newer_snapshot

[PeterBortas]

Got this a few times:

Apr 24 22:50:19  Downloading Pike snapshot...
./client.sh: 348: [: -rw-r--r-- 1 nobody nogroup 11250463 Apr 23 14:26 snapshot.tar.gz: unexpected operator
Apr 24 22:50:21  Running test "clang" in /home/zino/hack/xenofarm/client/pike-devel/b14.lysator.liu.se.

In my branch (better nodename pull request applied) this is the line

[ "$OLD" == "$NEW" ] || return 0

This should probably be solved with the normal X prefixing, but I don't get why it doesn't happens all the time if "-r" is what it complains about.

The problem is most likely that there's no such operator as '==' in /bin/test. It should just be a single '='.
