ddclient doesn't parse usev4, usev6, or related options per-host

[mgorbach]

TLDR: It appears that usev4, usev6 and related options like cmdv6 do not parse correctly when configured on a per-host basis.

I'm using 3.10.0_2, and have the following configuration file:

daemon=300              # check every 300 seconds
syslog=yes              # log update msgs to syslog
mail-failure=<redacted>
pid=/usr/local/var/run/ddclient.pid     # record PID in file.
ssl=yes                 # use ssl-support.  Works with

protocol=cloudflare
login=<redcated>
password=<redacted>
zone=<redacted>
ssl=yes
usev4=webv4
webv4=api.ipify.org
usev6=webv6
webv6=api64.ipify.org

my.host.one.com

usev6=cmdv6, cmdv6=/root/bin/get_some_ip.sh my.host.two.com

I can see that the usev6 and cmdv6 options do not come through for my.host.two.com. Instead, I get the global values. Below is the output of /usr/local/bin/ddclient -foreground -v -debug -verbose -noquiet -daemon=0. The use option does come through if you set it per-host, but the usev4, option also does not.
