As of Ubuntu 13.04 NetworkManager transmits nameserver information to
dnsmasq over D-Bus, but I believe it configures dnsmasq in the same way.

NetworkManager prepends domain names to the DNS server addresses so that
those addresses are only used for those domains, which are presumably
the (non-public) domains of the VPN.

original pre-VPN DNS servers

That is a bug in the routing configuration. I suggest you investigate
it. It could be a bug specific to Arch Linux or to your own system.
** Description changed:
- NetworkManager/dnsmasq does not set the DNS servers given by openvpn
+ NetworkManager/dnsmasq does not set the DNS servers given by the OpenVPN
server when I connect. I can see in my syslog that I do receive the name
- servers correctly along with all the routes:

DNS queries outside of VPN network)
