Tighten syntax checking for dhcp-range and clarify man page.

Commit 51967f9807 began treating SERVFAIL
as a successful response from an upstream server (thus ignoring future
responses to the query from other upstream servers), but a typo in that
commit means that REFUSED responses are accidentally being treated as
successful instead of SERVFAIL responses.

This commit corrects this typo and provides the behaviour intended by
commit 51967f9: SERVFAIL responses are considered successful (and will
be sent back to the requester), while REFUSED responses are considered
unsuccessful (and dnsmasq will wait for responses from other upstream
servers that haven't responded yet).

+version 2.76
+            Include 0.0.0.0/8 in DNS rebind checks. This range 
+	    translates to hosts on  the local network, or, at 
+	    least, 0.0.0.0 accesses the local host, so could
+	    be targets for DNS rebinding. See RFC 5735 section 3 
+	    for details. Thanks to Stephen Röttger for the bug report.
+
+	    Enhance --add-subnet to allow arbitrary subnet addresses.
+            Thanks to Ed Barsley for the patch.
+
+	    Respect the --no-resolv flag in inotify code. Fixes bug
+	    which caused dnsmasq to fail to start if a resolv-file 
+	    was a dangling symbolic link, even of --no-resolv set.
+	    Thanks to Alexander Kurtz for spotting the problem.
+
+	    Fix crash when an A or AAAA record is defined locally,
+	    in a hosts file, and an upstream server sends a reply
+	    that the same name is empty. Thanks to Edwin Török for
+	    the patch.
+
+	    Fix failure to correctly calculate cache-size when 
+	    reading a hosts-file fails. Thanks to André Glüpker 
+	    for the patch.
+
+	    Fix wrong answer to simple name query when --domain-needed
+	    set, but no upstream servers configured. Dnsmasq returned
+	    REFUSED, in this case, when it should be the same as when
+	    upstream servers are configured - NOERROR. Thanks to 
+	    Allain Legacy for spotting the problem.
+
+	    Return REFUSED when running out of forwarding table slots,
+	    not SERVFAIL.
+
+            Add --max-port configuration. Thanks to Hans Dedecker for
+	    the patch.
+
+	    Add --script-arp and two new functions for the dhcp-script.
+	    These are "arp" and "arp-old" which announce the arrival and
+	    removal of entries in the ARP or nieghbour tables.
+
+	    Extend --add-mac to allow a new encoding of the MAC address 
+	    as base64, by configurting --add-mac=base64
+ 
+	    Add --add-cpe-id option.
+
+            Don't crash with divide-by-zero if an IPv6 dhcp-range
+	    is declared as a whole /64.
+	    (ie xx::0 to xx::ffff:ffff:ffff:ffff) 
+	    Thanks to Laurent Bendel for spotting this problem.
+
+	    Add support for a TTL parameter in --host-record and
+	    --cname.
+
+	    Add --dhcp-ttl option.
+
+	    Add --tftp-mtu option. Thanks to Patrick McLean for the 
+	    initial patch.
+
+
+version 2.75
+            Fix reversion on 2.74 which caused 100% CPU use when a 
+	    dhcp-script is configured. Thanks to Adrian Davey for
+	    reporting the bug and testing the fix.
+
+	
+version 2.74
+            Fix reversion in 2.73 where --conf-file would attempt to
+	    read the default file, rather than no file.
+
+	    Fix inotify code to handle dangling symlinks better and
+	    not SEGV in some circumstances.
+
+	    DNSSEC fix. In the case of a signed CNAME generated by a
+	    wildcard which pointed to an unsigned domain, the wrong
+            status would be logged, and some necessary checks omitted.
+	
+
 version 2.73
             Fix crash at startup when an empty suffix is supplied to
 	    --conf-dir, also trivial memory leak. Thanks to
